Hi,

Please could someone help me find the greatest number of a string? Here's the code:

C#

if (dt.Rows.Count > 0)
                   {
                       int max = 0;
                       foreach (DataRow dr in dt.Rows)
                       {
                           bookNo = dr.ItemArray[0].ToString();
                           int i = Convert.ToInt32(bookNo.Substring(bookNo.Length - 1));
                           if (i > max)
                           {

                           }
                       }

Thanks

Just write

C#

max = i;

Inside the "if" statement. then at the end of your loop, max will contain the maximum value.

place your all data in generic List<int> & call max method of list.

XML

List<int> iList = new List<int>();
         //Here add values into iList
         int iMax = iList.Max();

Modify the below code according to your requirement.This piece of code worked for me.

C#

int length = 0;
           string longestTelephone = null;

           for (int i = 0; i < allTelephone.Count; i++)
           {

               if (length < allTelephone[i].Length)
               {
                   length = allTelephone[i].Length;
                   longestTelephone = allTelephone[i];
               }
           }

Hope this may help.
