如何在Visual Studio中基于字符串比较设置条件断点？

Question

这是我多年来不时尝试过的，而且从未成功过。我只想根据字符串相等性为Visual C ++ 2012设置条件断点。我想测试的变量是

string test;

我试过

test == "foo"
=> The breakpoint cannot be set. no operator "==" matches these operands

test == string("foo")
=> The breakpoint cannot be set. no operator "==" matches these operands

test.compare("foo") == 0
=> The breakpoint cannot be set. This expression has side effects and will not be evaluated.

strcmp(test.c_str(), "foo") == 0
=> The breakpoint cannot be set. This expression has side effects and will not be evaluated.

要在Visual Studio中使用，已经回答here。特别是，OBWANDO答案中提供的字符串可用于设置断点条件。但请注意，它有点麻烦。即使调试器已停止，您也会在遇到断点时收到警告消息。它似乎没有造成任何伤害。

您可以使用以下便携且简单的方式：

if (!test.compare("foo")) {
    int dummy = 0; // any statement, put breakpoint here
}
