************** JIT 调试 **************

[xelr233]

分析

这个 bug 在 Updater 构造函数中调用 FileVersionInfo.GetVersionInfo 时，传入的文件路径为空字符串。

从调用链来看：

Form1.Load → Updater.SilentCheck() → Updater..ctor(true) → FileVersionInfo.GetVersionInfo("")

常见触发场景：

1. 程序通过 dotnet publish 单文件发布 或 ReadyToRun 部署时，Assembly.Location 可能返回空字符串
2. 某些杀毒软件或系统策略清空了 PE 文件的版本信息查询路径
3. 在 Windows 11 22H2 + .NET 6.0.36 环境下，单文件部署场景更常见

建议修复

// Updater.cs - 构造函数中加空路径检查
public Updater(bool Silent)
{
    string assemblyPath = Assembly.GetExecutingAssembly().Location;
    
    // 防御性检查：单文件部署时 Location 可能为空
    if (string.IsNullOrEmpty(assemblyPath))
    {
        // 回退到 Process 模块路径或 AppContext.BaseDirectory
        assemblyPath = Environment.ProcessPath 
            ?? Path.Combine(AppContext.BaseDirectory, "FreeMove.exe");
    }

    if (!string.IsNullOrEmpty(assemblyPath) && File.Exists(assemblyPath))
    {
        var versionInfo = FileVersionInfo.GetVersionInfo(assemblyPath);
        // ... 原有逻辑
    }
}

复现环境确认

能否确认一下：

• 是通过 安装包 安装的，还是 便携版/单文件版？
• 这个问题是否在每次启动时都会触发，还是偶发？

这样我可以更精确地定位 root cause 并提交 PR。
