简单部分： 在项目属性 > 构建事件 中，添加一个“预构建事件命令行”，如下所示：
"D:\SomePath\MyAssemblyInfoPatcher.exe" "$(ProjectDir)Properties\AssemblyInfo.cs"
难点：您需要提供MyAssemblyInfoPatcher.exe，这是一个程序，它打开第一个参数指定的文件，并搜索其中的一行（忽略那里的值）：
[assembly: AssemblyVersion("8888.0.*")]
[assembly: AssemblyVersion("2016.11.05.2359")]
[assembly: AssemblyVersion("2016.1105.2359.1")]
[assembly: AssemblyVersion("8888.2016.1105.2359")]
程序从系统日期和时间中获取这些值，根据以下模式之一进行转换：
1. <yyyyMMddHHmmss>，即年月日时分秒
2. <yyyy-MM-dd HH:mm:ss>，即年-月-日 时:分:秒
并且重写文件。
yyyy.mm.dd.hhmm
yyyy.mmdd.hhmm.counter
arbitrary.yyyy.mmdd.hhmm
针对Visual Studio 2022，这里有一个新的解决方案，它需要修改csproj文件。
如何在Visual Studio 2022中使用日期/时间更改AssemblyInfo.cs AssemblyVersion并每天递增一个修订版本
从问题中复制：
以下是生成带有（年份、月份、日期、增量）版本的解决方案
此代码必须插入到*.csproj文件的</project>标签之前
<!-- Change AssemblyInfo.cs AssemblyVersion with date/time and increment revision daily by one in Visual Studio 2022 -->
<Target Name="AssemblyVersion" BeforeTargets="CoreCompile" DependsOnTargets="PrepareForBuild">
<PropertyGroup>
<!-- Define Constants -->
<AssemblyInfo>Properties\AssemblyInfo.cs</AssemblyInfo>
<AssemblyInfoContent>$([System.IO.File]::ReadAllText($(AssemblyInfo)))</AssemblyInfoContent>
<VersionRegex>(\[\s*assembly\s*:\s*AssemblyVersion\(\s*"(\d+)\.(\d+)\.(\d+)(\.)(\d+)("\)\s*\]))</VersionRegex>
<BuildAndRevisionRegex>(\d+\.\d+")</BuildAndRevisionRegex>
<!-- Parse Build and Revision from AssemblyInfo-->
<AssemblyVersion>$([System.Text.RegularExpressions.Regex]::Match('$(AssemblyInfoContent)', '$(VersionRegex)'))</AssemblyVersion>
<BuildAndRevision>$([System.Text.RegularExpressions.Regex]::Match('$(AssemblyVersion)', '$(BuildAndRevisionRegex)'))</BuildAndRevision>
<BuildAndRevision>$(BuildAndRevision.Remove($(BuildAndRevision.LastIndexOf('"')), 1))</BuildAndRevision>
<!-- Generate Build and Revision from AssemblyVersion -->
<Build>$(BuildAndRevision.SubString(0, $(BuildAndRevision.LastIndexOf('.'))))</Build>
<Revision>$(BuildAndRevision.SubString($([MSBuild]::Add($(BuildAndRevision.LastIndexOf('.')), 1))))</Revision>
<!-- Increment Revision by one if Build equal Current Day otherwise start from one as new Day Build-->
<Revision Condition ="$([System.DateTime]::Now.Day) == $(Build)">$([MSBuild]::Add($(Revision), 1))</Revision>
<Revision Condition ="$([System.DateTime]::Now.Day) != $(Build)">1</Revision>
<!-- New AssemblyVersion Block -->
<AssemblyVersion>[assembly: AssemblyVersion("$([System.DateTime]::Now.ToString("yyyy.M.d.$(Revision)"))")]</AssemblyVersion>
</PropertyGroup>
<!-- Write New AssemblyVersion Block to AssemblyInfo.cs file -->
<WriteLinesToFile File="$(AssemblyInfo)" Lines="$([System.Text.RegularExpressions.Regex]::Replace($(AssemblyInfoContent), $(VersionRegex), $(AssemblyVersion)))" Overwrite="true" />
</Target>
这可以通过MSBUILD完成。这里有一个很好的描述。 你不需要构建服务器。你可以在项目的BeforeBuild目标中调用自定义的MSBUILD目标。为此，使用编辑器打开csproj文件并定位文件末尾的此部分：
<!-- To modify your build process, add your task inside one of the targets below and uncomment it.
Other similar extension points exist, see Microsoft.Common.targets.
<Target Name="BeforeBuild">
</Target>
<Target Name="AfterBuild">
</Target>
-->
using System;
using System.IO;
using System.Linq;
namespace MyAssemblyInfoPatcher
{
internal class Program
{
static void Main(string[] args)
{
if (args.Length > 0)
{
string path = args[0].ToString();
Console.WriteLine(string.Format("Current App version is set to: {0}", path));
string now_date = DateTime.Now.ToString("yyyy.MM.dd.HHmm");
if (File.Exists(path))
{
string _AssemblyVersion = string.Empty;
string _AssemblyFileVersion = string.Empty;
var lines = File.ReadLines(string.Format(path));
for (int i = 0; i < lines.Count(); i++)
{
if (lines.ElementAt(i).ToString().StartsWith("[assembly: AssemblyVersion"))
{
_AssemblyVersion = lines.ElementAt(i).ToString();
}
else if (lines.ElementAt(i).ToString().StartsWith("[assembly: AssemblyFileVersion"))
{
_AssemblyFileVersion = lines.ElementAt(i).ToString();
}
}
string _replace_assembly = File.ReadAllText(path);
if (_AssemblyVersion != string.Empty)
{
_replace_assembly = _replace_assembly.Replace(_AssemblyVersion, string.Format("[assembly: AssemblyVersion(\"{0}\")]", now_date));
}
if (_AssemblyFileVersion != string.Empty)
{
_replace_assembly = _replace_assembly.Replace(_AssemblyFileVersion, string.Format("[assembly: AssemblyFileVersion(\"{0}\")]", now_date));
}
File.WriteAllText(path, _replace_assembly);
}
}
}
}
}
