我在 wpf 中编写了一个代码来显示指数,通过接受这两个数字,我创建了一个转换器函数和代码.. 但是在编写此代码后它显示错误,例如“Microsoft Visual Studio 遇到问题,它必须关闭”..然后当我们点击不发送时,它会关闭 Vs2010。这可能是什么问题?代码附在这里...
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;
}
}
}
