Format String Question

Brett

I am pulling the values from a database using a Querystring.

Example values: 
1.1
2.1
10.1
11.1

Is there a way to format the string so that it onlys shows the numbers before the decimal point?
Ex. 1.1 = 1, 10.1 = 10, etc.

I tried the code below but it only shows the first number.

string strNumber = Request.QueryString["Number"];

string strCode = strNumber.Substring(0,1);

this.Label1.Text = strCode.ToString();

Ok, I see. I wasn't sure how to get the decimal point location. Thanks for the example!

When you call strNumber.Substring(0, 1), it gives you a string starting at character 0 and ending at character 1. In other words, it's giving you just the first character. What you want is all the characters to the left of the decimal point. So:

int x = strNumber.IndexOf(".");    // Get the location of the decimal point.

if (x == -1)    // -1 means there was no decimal point found.
     Label1.Text = strNumber;

else
     Label1.Text = strNumber.Substring(0, x);   // Get all the characters to the left of the decimal point.
