Convert textbox value to another data type in Windows Store with C#

Question

Sorry for this question. I just got confused by the code to convert or parse value from textbox to int, float, double, etc in windows store. I'm a C# user and I tried this code

block1 = Convert.ToDouble(text1.Text); or block1 = double.Parse(text1.Text);

those method didn't work for me, does anybody can help me out? Thank you.

If you want to be able to easily select what type you want to covert the string to (int, double, float) you could make a simple method to convert the string.

Something like

private T ConvertTo<T>(string value) where T : IConvertible
{
    try
    {
      return (T)Convert.ChangeType(value, typeof(T));
    }
    catch (Exception)
    {
    }
    return default(T);
}

Usage:

string value = "33";

int intVal = ConvertTo<int>(value);
float floatVal = ConvertTo<float>(value);
double doubleVal = ConvertTo<double>(value);
