String 如何将字符串（culture！=“en-US”转换为int C#2005

2005年，我在Program.cs中设置了如下文化：

CultureInfo myCulture = new CultureInfo("bn-IN");// like "en-US", "ja-JP" etc...
Thread.CurrentThread.CurrentCulture = myCulture;
Thread.CurrentThread.CurrentUICulture = myCulture;
Application.CurrentCulture = myCulture;

然后打开应用程序后，我选择我的键盘，点击键盘1，输入我的语言版本1。现在我想把它转换成整数，这样我就可以进行加法，减法等等

CultureInfo myCulture = Application.CurrentCulture;
myCulture.NumberFormat.DigitSubstitution = DigitShapes.NativeNational;
int i = Convert.ToInt32(textbox1.Text, myCulture.NumberFormat);// this line throws exception with message "Input string was not in a current format"

那么，如何将另一个区域性（而不是“en-US”）中的字符串转换为整数呢

CultureInfo oldCulture = Thread.CurrentThread.CurrentCulture;
        Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");

在这里输入不同文化的价值观，然后回到旧文化

Thread.CurrentThread.CurrentCulture = oldCulture;
