RuntimeWrappedException 类

定义

包装不是从 Exception 类派生的异常。Wraps an exception that does not derive from the Exception class. 此类不能被继承。This class cannot be inherited.

public ref class RuntimeWrappedException sealed : Exception
public sealed class RuntimeWrappedException : Exception
[System.Serializable]
public sealed class RuntimeWrappedException : Exception
type RuntimeWrappedException = class
    inherit Exception
[<System.Serializable>]
type RuntimeWrappedException = class
    inherit Exception
Public NotInheritable Class RuntimeWrappedException
Inherits Exception
继承
RuntimeWrappedException
属性

示例

下面的代码示例演示如何 String 在 c + + 中将对象作为异常引发,并使用对象捕获该对象 RuntimeWrappedExceptionThe following code example demonstrates how to throw a String object as an exception in C++ and catch it using a RuntimeWrappedException object.

using namespace System;
using namespace System::Runtime::CompilerServices;

[assembly:RuntimeCompatibilityAttribute(WrapNonExceptionThrows = true)]; 

void run()
{
    try
    {
        throw gcnew String("This is a string");

    }
    catch(RuntimeWrappedException^ e)
    {
        Console::WriteLine("RuntimeWrappedException caught!");
    }
}

int main()
{
    run();

    return 0;
}

注解

某些语言(如 c + +)允许你引发任何托管类型的异常。Some languages, such as C++, allow you to throw exceptions of any managed type. 其他语言(如 Microsoft c # 和 Visual Basic)要求每个引发的异常都是从 Exception 类派生的。Other languages, such as Microsoft C# and Visual Basic, require that every thrown exception be derived from the Exception class. 为了保持语言之间的兼容性,公共语言运行时 (CLR) 包装对象中不是从派生的对象 Exception RuntimeWrappedExceptionTo maintain compatibility between languages, the common language runtime (CLR) wraps objects that do not derive from Exception in a RuntimeWrappedException object.

您可以使用 RuntimeCompatibilityAttribute 类来指定异常是否应显示在程序集的 catch 块内部和异常筛选器中。You can use the RuntimeCompatibilityAttribute class to specify whether exceptions should appear wrapped inside catch blocks and exception filters for an assembly. 许多语言编译器(包括 Microsoft c # 和 Visual Basic 编译器)默认应用此属性以指定换行行为。Many language compilers, including the Microsoft C# and Visual Basic compilers, apply this attribute by default to specify the wrapping behavior.

请注意,即使你使用 RuntimeCompatibilityAttribute 类指定不需要包装异常,运行时仍会对异常进行包装。Note that the runtime still wraps exceptions even if you use the RuntimeCompatibilityAttribute class to specify that you do not want them wrapped. 在这种情况下,只会在 catch 块或异常筛选器内解包异常。In this case, exceptions are unwrapped only inside catch blocks or exception filters.
