可通过下载demo运行即可。
原理：通过csproject项目文件中的Target标签，实现在项目编译之前对项目版本号进行修改，避免手动修改；
1.基础版
效果图如下
部分脚本如下：
<Project>
<PropertyGroup><PreBuildEvent></PreBuildEvent></PropertyGroup><Target Name="SetAssemblyVersion" BeforeTargets="BeforeBuild"><PropertyGroup><Year>$([System.DateTime]::Now.ToString("yy"))</Year><MonthDay>$([System.DateTime]::Now.ToString("MMdd"))</MonthDay></PropertyGroup><Message Text="Setting AssemblyVersion to 1.0.$(Year).$(MonthDay)" Importance="high" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="//using System.Reflection;" Overwrite="true" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTitle("MyAPPTitle")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyDescription("2021.03.29")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyConfiguration("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCompany("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyProduct("MyPro")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCopyright("Copyright ? CCC")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTrademark("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCulture("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Runtime.InteropServices.ComVisible(false)]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Windows.ThemeInfo(System.Windows.ResourceDictionaryLocation.None, System.Windows.ResourceDictionaryLocation.SourceAssembly)]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyVersion("01.00.00$(Year).$(MonthDay)")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyFileVersion("01.00.00$(Year).$(MonthDay)")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyInformationalVersion("01.00.00$(Year).$(MonthDay)")]" Overwrite="false" /></Target>
</Project>
2.进阶版
部分项目要自定义生成版本号，可通过自定义类的方式来实现。
1.新建项目ClassLibrary1
2.引用系统类库sing Microsoft.Build.Framework;；using Microsoft.Build.Utilities;
3.新建类GenerateVersionTask
public class GenerateVersionTask : Task{[Output]public int Version { get; set; }public override bool Execute(){// 生成版本号的逻辑Version = GetVisitCount();return true;}private const string DataFilePath = "visit_counter.dat";public static int GetVisitCount(){// 读取存储的数据int visitCount = 0; DateTime lastVisitDate = DateTime.Now;ReadData(ref visitCount, ref lastVisitDate);// 获取当前日期DateTime today = DateTime.Today;// 检查是否是新的一天if (lastVisitDate < today){// 重置访问次数visitCount = 0;lastVisitDate = today;}// 增加访问次数visitCount++;// 保存数据SaveData(visitCount, lastVisitDate);// 返回访问次数return visitCount;}private static void ReadData(ref int count, ref DateTime countdate){if (File.Exists(DataFilePath)){string[] lines = File.ReadAllLines(DataFilePath);if (lines.Length == 2){int visitCount = int.Parse(lines[0]);DateTime lastVisitDate = DateTime.Parse(lines[1]);count = visitCount; countdate = lastVisitDate;}}else{File.Create(DataFilePath);count = 0; countdate = DateTime.Now;}}private static void SaveData(int visitCount, DateTime lastVisitDate){string[] lines = { visitCount.ToString(), lastVisitDate.ToString() };File.WriteAllLines(DataFilePath, lines);}}
4.增加脚本
<UsingTask TaskName="GenerateVersionTask" AssemblyFile="$(TargetDir)\ClassLibrary1.dll" />
和
<GenerateVersionTask><Output TaskParameter="Version" PropertyName="MyVersion" /></GenerateVersionTask>
效果如图所示
<UsingTask TaskName="GenerateVersionTask" AssemblyFile="$(TargetDir)\ClassLibrary1.dll" /><Target Name="SetAssemblyVersion" BeforeTargets="BeforeBuild"><PropertyGroup><Year>$([System.DateTime]::Now.ToString("yy"))</Year><MonthDay>$([System.DateTime]::Now.ToString("MMdd"))</MonthDay></PropertyGroup><GenerateVersionTask><Output TaskParameter="Version" PropertyName="MyVersion" /></GenerateVersionTask><Message Text="Generated Version: $(MyVersion)" Importance="high" /><Message Text="Setting AssemblyVersion to 01.0$(MyVersion).00$(Year).$(MonthDay)" Importance="high" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="//using System.Reflection;" Overwrite="true" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTitle("MyAPPTitle")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyDescription("2021.03.29")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyConfiguration("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCompany("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyProduct("MyPro")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCopyright("Copyright ? CCC")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTrademark("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCulture("")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Runtime.InteropServices.ComVisible(false)]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Windows.ThemeInfo(System.Windows.ResourceDictionaryLocation.None, System.Windows.ResourceDictionaryLocation.SourceAssembly)]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyVersion("01.0$(MyVersion).00$(Year).$(MonthDay)")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyFileVersion("01.0$(MyVersion).00$(Year).$(MonthDay)")]" Overwrite="false" /><WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyInformationalVersion("01.0$(MyVersion).00$(Year).$(MonthDay)")]" Overwrite="false" /></Target>
