安全处理异常时避免第一次机会异常消息

问题描述：

以下代码捕获 EOS 异常

The following bit of code catches the EOS Exception

using (var reader = new BinaryReader(httpRequestBodyStream)) {

    try {
        while (true) {
            bodyByteList.Add(reader.ReadByte());
        }
    } catch (EndOfStreamException) { }
}

那么为什么我的控制台仍然会收到第一次异常?

So why do I still receive first-chance exceptions in my console?

在 mscorlib.dll 中发生类型为System.IO.EndOfStreamException"的第一次机会异常

A first chance exception of type 'System.IO.EndOfStreamException' occurred in mscorlib.dll

有没有办法隐藏这些第一次机会异常消息?

Is there a way to hide these first chance exception messages?

答

第一次机会"异常的要点是您看到它们是预处理程序，以便您可以在调试期间在抛出点停止.第二次机会"异常是没有合适的处理程序的异常.有时您想捕获第一次机会"异常，因为即使有人在捕获异常，也必须查看抛出时发生的情况.

The point of "first-chance" exceptions is that you're seeing them pre-handler so that you can stop on them during debugging at the point of throwing. A "second-chance" exception is one that has no appropriate handler. Sometimes you want to catch "first-chance" exceptions because it's important to see what's happening when it's being thrown, even if someone is catching it.

没有什么可担心的.这是正常行为.

There's nothing to be concerned with. This is normal behavior.
