您好如何使用vs2003在托管代码c ++中使用foreach循环。

4 个解决方案

I've never used it, but this MSDN article indicates the general syntax is just:

我从来没有使用它,但这篇MSDN文章表明一般语法只是:

for each(Type t in IEnumerable)
{

}

#2


Matthew is mostly correct, but here's a working block of code;

马修大多是正确的,但这是一个有效的代码块;

///////
array<Type^>^ iterate_me = gcnew array<Type^>(2);
iterate_me[0] = Type::GetType("Type");
iterate_me[1] = Type::GetType("System.Int32");
///////

for each(Type^ t in iterate_me)
    Console::WriteLine(t);

The changes were Type is a reference class, so you use "Type^" not "Type" and you need an actual object reference (iterate_me)...

更改是Type是一个引用类,所以你使用“Type ^”而不是“Type”,你需要一个实际的对象引用(iterate_me)...

#3


Something like:

String ^ MyString = gcnew String("abcd");

for each ( Char c in MyString )

    Console::Write(c);

#4


I don't think that VC++ has foreach

我认为VC ++不具备预期性
