向量'无操作符'[]在Visual Studio中匹配这些操作数的错误 [英] Vector 'no operator "[]" matches these operands' error in Visual Studio watch

问题描述

在Visual Studio 2012中逐步执行以下示例代码时：

  std :: vector< int&测试; 
 test.resize（1）; 
 test [0] = 4; 
  

我可以在测试中设置手表，并检查其第0个元素。但是，如果我在test [0]上设置了一个watch，我得到错误no operator[]匹配这些操作数：

如何检查test [0]直接？

解决方案

我发现一个解决方案不依赖于类的内部。扩展形式的操作符调用似乎对我有用。在这种情况下，它是以下代码：

  v.operator []（0）
  
 
 
 
我在Visual C ++ 2012中测试了它。
 
When stepping through the following sample code in Visual Studio 2012:
std::vector<int> test;
test.resize(1);
test[0] = 4;
I can set a watch on test and inspect its 0th element.  However, if I set a watch on test[0], I get the error 'no operator "[]" matches these operands':



How can I inspect the value of test[0] directly?
解决方案
I found one solution which does not depend on the internals of the class. The expanded form of the operator call seems to work for me. In this case it's the following code:
v.operator[](0)
I tested it in Visual C++ 2012.
