how to convert string array to integer array

Hi,

Try this with your code.

public static class ExtensionMethods
{

  public static string[] ToStringArray(this int[] intArray) 
  {
      return Array.ConvertAll(intArray, delegate(int intParameter) { return intParameter.ToString(); });
  }

  public static int[] ToIntArray(this string[] strArray) 
  {
   return Array.ConvertAll(strArray, delegate(string intParameter) { return int.Parse(intParameter.ToString()); });
  }

}

This is extension methods you can use this your project.

Try the following. Notice that if an element of the string array cannot be parsed to an integer, then zero is inserted into the integer array.
