在c#中确定try.catch ...中的异常类型 [英] Determine exceptions type in try... catch... in c#

问题描述

我想确定我的catch块内的Exception类型:

I want to determine the Exception type inside my catch block:

try 
{
    // ...
}
catch (Exception ex)
{
    if (ex == UnauthorizedAccessException)  // ??
    {
        // ...
    }
    else
    {
        // ...
    }
}

推荐答案

您可以尝试下面的代码.

You can try like bellow code.

try
{
    // do something that could throw an exception
}
catch(Exception e)
{
    if (e is FileNotFoundException)
    {
        // •••
    }
    else if (e is DivideByZeroException)
    {
        // •••
    }
    else throw;
}

谢谢

您可以使用GetType()函数来确定在Catch块中生成哪个异常.

You can use GetType() function to determine which exception is generate in Catch block.

try
         {

         }
         catch (Exception ex)
         {
             MessageBox.Show(ex.GetType().ToString()); // It will Display Message type
         }

try
{
    // ...
}
catch (UnauthorizedAccessException)
{
    // ...
}
catch (Exception)
{
    // ...
}

像这样的东西.

Something like this.
