查看我的答案问题： C＃app已安装但未运行 [ ^ ]



在您的情况下，如果您的代码非常大，请按照Mehdi Gholam的建议进行尝试main方法，通常位于Program.cs文件中。



以下示例适用于Windows窗体应用程序。

See my answer for a similar problem: C# app Installed but does not run[^]

In your case, if your code is very large follow the advice from Mehdi Gholam and put a try-catch in the main method, usually located in the file Program.cs.

The example below applies to a Windows Form application.

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        try
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new FormMain());
        }
        catch (Exception ex)
        {
            // Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
            // returns a folder that is usually allowed to write files to
            string filePath = System.IO.Path.Combine(
                Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
                 "MyApplication_CrashInfo.txt");
            System.IO.File.WriteAllText(filePath, ex.ToString());
        }
    }
}

将MyApplication更改为您的应用程序名称。

使用 Exception.ToString（） [ ^ ]你得到的完整的堆栈跟踪，它应该指出代码抛出异常的行。



有关Environment.SpecialFolder枚举 [ ^ ]



当您收到错误消息时，您可以希望缩小到代码失败的位置并解决问题。



[已更新]

确保d你希望在exists中创建文件的irectory，你可以尝试这段代码。

Change MyApplication to your application name.
By using Exception.ToString()[^] you get the full stack trace and it should point out the line where the code throws the exception.

See this link for more info about Environment.SpecialFolder Enumeration[^]

When you get the error message you can then hopefully narrow down to where your code fails and fix the problem.

[Updated]
To make sure the directory you want to create the file in exists, you can try this code.

string dummyPath = @"C:\Temp\Tes\Test\Test.txt";
string dir = System.IO.Path.GetDirectoryName(dummyPath);
if (!System.IO.Directory.Exists(dir))
    System.IO.Directory.CreateDirectory(dir);

System.IO.File.Create(dummyPath);

嗯..我真的认为问题是你所在的目录试图写不存在。尝试在你的getLogFilePath方法中添加它：

Well..i really think the problem is the directory where you are trying to write doesn't exists. Try adding this in your getLogFilePath method:

string logFilePath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\\gatesv";
if (!Directory.Exists(logFilePath))
{
    Directory.CreateDirectory(logFilePath);
}
