我使用PowerShell脚本和预构建事件的组合得到了它：
脚本如下（在项目目录中保存为gitversion.ps1：

$gitVersionJson = dotnet gitversion /output json
$By = [System.Text.Encoding]::Unicode.GetBytes($gitVersionJson)
$output =[Convert]::ToBase64String($By)

"using System;
using System.Collections.Generic;
using System.Text;
using System.Text.Json;

class GitVersion {
    private static Dictionary<string, object> _values;
    private static Dictionary<string, object> Values {
        get {
            if (_values == null) {              
                byte[] data = Convert.FromBase64String(""$output"");
                string decodedString = Encoding.Unicode.GetString(data);
                _values = JsonSerializer.Deserialize<Dictionary<string, object>>(decodedString);
            }

            return _values;
        }
    }

    public static object MajorMinorPatch {
        get {
            return Values[""MajorMinorPatch""];
        }
    }

}
" | Out-File GitVersion.cs

"Generated GitVersion.cs" | Write-Output

然后，作为预构建事件，我在Build设置中添加了以下内容：

powershell -ExecutionPolicy Bypass -NoProfile -NonInteractive -File "$(ProjectDir)gitversion.ps1"

或者在myproject.csproj中：

<Target Name="PreBuild" BeforeTargets="PreBuildEvent">
   <Exec Command="powershell -ExecutionPolicy Bypass -NoProfile -NonInteractive -File &quot;$(ProjectDir)gitversion.ps1&quot; " />
</Target>

这将创建一个GitVersion类，可以在代码中使用：

Console.WriteLine(GitVersion.MajorMinorPatch);
