我寫了一個代碼在wpf顯示指數,通過接受兩個數字 因爲我已經創建了一個轉換器功能和代碼..但是當寫完這個後代碼它顯示錯誤,如 「Microsoft Visual Studio遇到問題,它必須關閉」..然後當我們點擊不要發送它關閉Vs2010。 這可能是什麼問題?代碼接在這裏......爲什麼VisualStudio關閉時,我寫這個Wpf xmal代碼
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;
}
}
}

當您重新打開VS會發生什麼由
ObjectDataProvider
參考呢? – 2012-04-26 09:19:46
