C# Directory.CreateDirectory 停止工作

Question

我有一个 C# 应用程序，它在许多 pc、笔记本电脑上都能正常工作。但是，我复制到我客户的电脑（4TB 硬盘 - windows 10 家庭版），我的应用程序停止工作！

我尝试将 MessageBox.Show() 放在某行中以查找损坏的地方。它停在 Directory.CreateDirectory(@"D:\mypath")

PC有D:不知道为什么坏了

这是我的代码：

string now = DateTime.Now.ToString("HH_mm_ss");
string strDuongDan;

strDuongDan = @"D:\VideoLuuTru\" + DateTime.Now.Month.ToString() + "_" + DateTime.Now.Year.ToString();

if (!Directory.Exists(strDuongDan))
    Directory.CreateDirectory(strDuongDan);

string strDuongDan2 = strDuongDan + "\" + DateTime.Now.ToString("dd"); ;

if (!Directory.Exists(strDuongDan2))
    Directory.CreateDirectory(strDuongDan2);

我怎样才能准确地跟踪我的错误，我的代码有什么问题吗？它运行在许多 PC 上运行完美，但在这台 PC 上，它坏了。

我的问题是否与大硬盘有关space？

我客户的 IT 人员在他的笔记本电脑（Windows 10 Home）上安装了我的应用程序，并在这台电脑上安装了相同的 windows。我的应用程序运行在他的笔记本电脑上没有错误

谢谢！

编辑： 我的功能和我的错误：

函数：

 public void makevideo()
        {
            string now = DateTime.Now.ToString("HH_mm_ss");
            string strDuongDan;

            strDuongDan = @"D:\VideoLuuTru\" + DateTime.Now.Month.ToString() + "_" + DateTime.Now.Year.ToString();

            if (!Directory.Exists(strDuongDan))
                Directory.CreateDirectory(strDuongDan);

            string strDuongDan2 = strDuongDan + "\" + DateTime.Now.ToString("dd"); ;
            if (!Directory.Exists(strDuongDan2))
                Directory.CreateDirectory(strDuongDan2);
        }

调用函数

 ThreadStart childref = new ThreadStart(() => makevideo());

 Thread childThread = new Thread(childref);

 try { childThread.Start(); }
 catch (Exception ex)
 {
     MessageBox.Show(ex.ToString());
  }

错误： **

Answer 1

我通常不建议捕获这样的错误

但是您可以使用记录器，或者如果您真的必须将错误推送到 MessageBox。至少你会知道例外

或者您可以检查事件日志查看器，如果您的应用程序崩溃，它会为您提供有关发生了什么的线索。

最后，这很可能是许可问题，但谁知道呢。确保您的客户端已授予对该目录的适当权限，或者运行您的应用程序处于提升的权限

try
{
    // Note you don't need to check if a directory exists before you create it
    // it does it for you
    // if (!Directory.Exists(strDuongDan))
    Directory.CreateDirectory(strDuongDan);
}
catch(Exception ex)
{
   // log here
   // or
   MessageBox.Show("Error : " + ex.Message)
}
