变量“MyException"已声明但从未使用

The variable #39;MyException#39; is declared but never used(变量“MyException已声明但从未使用)

问题描述

我需要清除此警告:

try
{
    doSomething()
}
catch (AmbiguousMatchException MyException)
{
    doSomethingElse()
}

编译器告诉我:

变量MyException"已声明但从未使用过

The variable 'MyException' is declared but never used

我该如何解决这个问题.

How can I fix this.

推荐答案

1. 你可以这样删除它:

1. You can remove it like this:

try
{
    doSomething()
}
catch (AmbiguousMatchException)
{
    doSomethingElse()
}

try
{
    doSomething()
}
#pragma warning disable 0168
catch (AmbiguousMatchException exception)
#pragma warning restore 0168
{
    doSomethingElse()
}

其他熟悉的警告禁用

#pragma warning disable 0168 // variable declared but not used.
#pragma warning disable 0219 // variable assigned but not used.
#pragma warning disable 0414 // private field assigned but not used.
