我写了一个代码在wpf显示指数,通过接受两个数字 因为我已经创建了一个转换器功能和代码..但是当写完这个后代码它显示错误,如 “Microsoft Visual Studio遇到问题,它必须关闭”..然后当我们点击不要发送它关闭Vs2010。 这可能是什么问题?代码接在这里......为什么VisualStudio关闭时,我写这个Wpf xmal代码
namespace WpfTutSamples
{
public partial class Exponential : Window
{
public Exponential()
{
InitializeComponent();
}
public double GetValue(double number, double exponent)
{
double value = Math.Pow(number, exponent);
return value;
}
}
}

当您重新打开VS会发生什么由
