检查返回值而不将其赋值给变量 [英] Inspect return value without assign it to a variable

问题描述

我有以下代码剪切：

...
var tpc = new ThirtPartyClass();

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

ExecuteCommand（）方法返回一个含有一些信息的int值。
对于调试，我想知道这个返回值。但是我不想将结果分配给变量（var result = 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()).

VisualStudio 2010中有可能在调试期间，检查此返回值而不分配给临时变量？

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

提前感谢您的建议

编辑：最后，此功能已添加到 VS2013

推荐答案

IntelliTrace在VS2010中，通过切换到通话视图，然后选中自动窗口：

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

但即使没有，不要担心;如果您不使用该变量（除非在暂停时查看调试器），那么在发布版本中，它将被删除并替换为只有一个pop（这是你得到的，如果你没有收到回报价值在第一位）。

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();
}

编译为：

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

note no .locals and no stloc 。

note no .locals and no stloc.

对于Resharper，使用：

For Resharper, use:

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