How to rewrite an IF statement in C# to ensure that an extract file has an output field with a fixed length of 10 and with leading zeros?

I am writing my first C# console application using Visual Studio 2005.
My goal is to have my application read an input file and create an extract file.
Do you know how I could rewrite the following C# code "IF statement" for 1 of my input fields?
2 examples of the input record value are as follows, for the input field titled image_offset:
1)   <csc:image_offset>02894</csc:image_offset>
or
2)   <csc:image_offset>0</csc:image_offset>
 
For the output of this field, the output field is titled "GROUP OFFSET"
The output field should be formatted with leading zeros and with a fixed field length of 10?
The output for the 1st example above should be as follows:
GROUP_OFFSET:0000002894 (6 leading zeros)
The output for the 2nd example should be as follows:
GROUP_OFFSET:0000000000 (10 zeros)

My C# IF statement which needs to be modified is as follows:

if (reader.Name == "csc:image_offset")
                    {
                       arr1[i,17] = "GROUP_OFFSET:" + reader.ReadElementContentAsString();
                    }


Here is an example of an input file for this application:
-------------------------------
<?xml version="1.0"?>
<csc:CIndex_File
    xmlns:csc="http://c.com/xml/CIndex_File">
<csc:header>

-----------------------------------------------------
My program is as follows:

using System;
using System.Xml;
using System.IO;
namespace ReadXml1
{
     class Class1
     {        
         static void Main(string[] args)
         {
            int i = 0;
            string[,] arr1 = new string[1000,19];
            int iCheckNumber = 0;
           
            XmlTextReader reader = new XmlTextReader("C:\\rbc.xml");
     
            StreamWriter sw = new StreamWriter("C:\\output.txt");

            while (reader.Read())
             
            {
                if (reader.NodeType == XmlNodeType.Element)
                {
                    if (reader.Name == "csc:check_number")
                    {
                        iCheckNumber = iCheckNumber + 1;
                        arr1[i,0] = "COMMENT: CHECK NUMBER #" + iCheckNumber;
                        arr1[i,1] = "GROUP_FIELD_NAME:CheckNumber";
                        arr1[i,2] = "GROUP_FIELD_VALUE:" + reader.ReadElementContentAsString();        
                    }
                    if (reader.Name == "csc:routing_transit")
                    {
                        arr1[i,3] = "GROUP_FIELD_NAME:RoutingTransit";
                        arr1[i,4] = "GROUP_FIELD_VALUE:" + reader.ReadElementContentAsString();
                        arr1[i,5] = "GROUP_FIELD_NAME:BankName";
                        arr1[i,6] = "GROUP_FIELD_VALUE:RBC BANK";
                    }
                    if (reader.Name == "csc:account_number")
                    {
                        arr1[i,7] = "GROUP_FIELD_NAME:BankAccountNo";
                        arr1[i,8] = "GROUP_FIELD_VALUE:" + reader.ReadElementContentAsString();
                    }
                    if (reader.Name == "csc:amount")
                    {
                        arr1[i,9] = "GROUP_FIELD_NAME:CheckAmount";
                        arr1[i,10] = "GROUP_FIELD_VALUE:" + reader.ReadElementContentAsString();
                        arr1[i,11] = "GROUP_FIELD_NAME:CpscNo";
                        arr1[i,12] = "GROUP_FIELD_VALUE:00000000";                        
                    }
                    if (reader.Name == "csc:processing_date")
                    {
                        arr1[i,13] = "GROUP_FIELD_NAME:CheckPaidDate";
                        arr1[i,14] = "GROUP_FIELD_VALUE:" + reader.ReadElementContentAsString();
                        arr1[i,15] = "GROUP_FIELD_NAME:OfficeNo";
                        arr1[i,16] = "GROUP_FIELD_VALUE:000";  
                    }
                    if (reader.Name == "csc:image_offset")
                    {
                        arr1[i,17] = "GROUP_OFFSET:" + reader.ReadElementContentAsString();
                    }
                    if (reader.Name == "csc:image_length")
                    {
                        arr1[i,18] = "GROUP_LENGTH:" + reader.ReadElementContentAsString();
                        i++;
                    }                    
                }            
            }

            for (int iter = 0; iter < i; iter++)
            {
                for (int j = 0; j < 19; j++)
                {
                    sw.WriteLine(arr1[iter,j]);
                }
            }
            sw.Close();
            reader.Close();    
         }                  
     }
}

My output file would look like the following:

COMMENT: CHECK NUMBER #1
GROUP_FIELD_NAME:CheckNumber
GROUP_FIELD_VALUE:000000000000001
GROUP_FIELD_NAME:RoutingTransit
GROUP_FIELD_VALUE:000000007

GROUP_FIELD_VALUE:00000000
GROUP_FIELD_NAME:CheckPaidDate

GROUP_FIELD_NAME:OfficeNo
GROUP_FIELD_VALUE:000
GROUP_OFFSET:0000002894
GROUP_LENGTH:0000016685
COMMENT: CHECK NUMBER #2

Use the PadLeft function of the string, see below.

            string myincomingString = txtIn.Text.Trim();   // 000145   and it needs to be 0000000145
            myincomingString = myincomingString.PadLeft(10, '0');
            MessageBox.Show(myincomingString);

The modified code is here:

            string strTemp = reader.ReadElementContentAsString();
            if (reader.Name == "csc:image_offset")
            {
                arr1[i, 17] = "GROUP_OFFSET:" + strTemp.PadLeft(10,'0');
            }

Or this may be better:

            if (reader.Name == "csc:image_offset")
            {
                string strTemp = reader.ReadElementContentAsString();
                arr1[i, 17] = "GROUP_OFFSET:" + strTemp.PadLeft(10,'0');
            }
