// This example is from http://idealprogrammer.com
// It shows how you can use StrComp syntax in C-Sharp ASP.NET
 
//****************************************************************************************
// Example #1: 	StrComp(string1,string2,comparemethod) - returns integer
// Returns -1, 0, or 1, based on the result of a string comparison. 
// -1  String1 sorts ahead of String2
//  0  String1 is equal to String2
//  1  String1 sorts after String2
// comparemethod - Optional. Specifies the type of string comparison. If Compare is omitted, 
// the Option Compare setting determines the compare method 
//****************************************************************************************
 
public partial class StringManipulation_StrComp : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Label1.Text = "Example #1: 	StrComp(string1,string2,comparemethod)";
 
        string strString1 = "XYZ";
        string strString2 = "xyz";
 
        TextBox1.Text = string.Compare(strString1, strString2, true).ToString(); //Returns 0
        TextBox2.Text = string.Compare(strString1, strString2, false).ToString(); //Returns 1
        strString2 = "ABC";
        TextBox3.Text = string.Compare(strString1, strString2, false).ToString(); //Returns 1
 
    }
}
