VC++.net 的第一个简单例子
vc++.net 基本上保留了vc++的东西，但是在细节上也有了些差别，和c#的差别是非常大。下面是摸索的一个小小例子的一段代码。从代码可以看出，声明所有引用类型的对象的时候，要有一个^
比如：System::String^ strA;
<div style="padding-right: 5.4pt; padding-left: 5.4pt; background: #e6e6e6; padding-bottom: 4px; width: 95%; padding-top: 4px;">http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedBlockStart.gifhttp://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedBlock.gifprivate:System::Voidbutton1_Click(System::Object^sender,System::EventArgs^e)...{
