本文介绍了检查返回值,而不把它分配给一个变量的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有以下代码剪断:

...
var tpc = new ThirtPartyClass();

tpc.ExecuteCommand();
tpc.ExecuteCommand();
...



的ExecuteCommand()方法返回的一些信息的int值。
。对于调试,我想知道这个返回值。但我不希望的结果分配给一个变量(VAR的结果= tpc.ExecuteCommand())。

The ExecuteCommand() method returns a int value with some information. For debugging, I want to know this return values. But I don't want to assign the result to a variable (var result = tpc.ExecuteCommand()).

有没有在2010年的VisualStudio调试过程中一种可能性,以?检查,而不把它分配给一个临时变量这个返回值

Is there in VisualStudio 2010 a possibility during debugging, to inspect this return value without assign it to a temporary variable?

在此先感谢您的建议

编辑:最后,该功能已被添加到 VS2013

推荐答案

您可以做到这一点在的IntelliTrace VS2010,通过切换到电话查看,然后检查自动窗口:

You can do that with IntelliTrace in VS2010, by switching to the "Calls View" then checking the Autos window:

但是,即使没有那个,不用担心它;如果你不使用变量(除了通过寻找在调试器暂停时),然后在发布版本将被删除,只用流行取代(这是你得到什么,如果你没有赶上回。首先值)

But even without that, don't worry about it; if you don't use the variable (except by looking in the debugger when paused), then in a release build it will be removed and replaced with just a "pop" (which is what you get if you don't catch the return value in the first place).

所以:

static void Main()
{
    int i = SomeMethod();
}



编译如下:

Compiles as:

.method private hidebysig static void Main() cil managed
{
    .entrypoint
    .maxstack 8
    L_0000: call int32 Program::SomeMethod()
    L_0005: pop 
    L_0006: ret 
}

请注意没有 .locals 并没有 stloc

ReSharper的,使用:

For Resharper, use:

// ReSharper disable UnusedVariable
    int i = SomeMethod();
// ReSharper restore UnusedVariable
