I am writing my first C# console application using Visual Studio 2005. Do you know how I could rewrite the following C# code "IF statement" so that the amount field is displayed as a numeric value with an explicit decimal point?

An example of one of my daily input files is as follows:

Assuming the input amount field has the following dollar value with an implicit decimal and the output should contain leading zeros with an explicit decimal point and has a field length of 10,
how would you revise the following IF statement?

  if (reader.Name == "csc:amount")
                    {
                        //sw.WriteLine("GROUP_FIELD_NAME:CheckAmount");
                        //sw.WriteLine("GROUP_FIELD_VALUE:" + reader.ReadElementContentAsString());

Input field:      <csc:amount>0000000100</csc:amount>

Output fields: GROUP_FIELD_NAME:CheckAmount
                      GROUP_FIELD_VALUE:0000001.00

My output file would look like the following:

Here's how you can print it in the way you want.
Arun

string strVal = "000000200";
string newStrVal = strVal.Substring(0, strVal.Length - 2) + "." + strVal.Substring(strVal.Length - 2);
Console.WriteLine(newStrVal);

You can make the above logic as a method and just pass the input value to the method.
arr1[i,9] = "GROUP_FIELD_NAME:CheckAmount";
arr1[i,10] = "GROUP_FIELD_VALUE:" + GetFormattedValue(reader.ReadElementContentAsString());
private string GetFormattedValue(string strVal)
{
      return strVal.Substring(0, strVal.Length - 2) + "." + strVal.Substring(strVal.Length - 2);
}

Where would you place the method GetFormattedValue in the following program?

using System;
using System.Xml;
using System.IO;
namespace ReadXml1

            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())
             
            {

                    {
                        iCheckNumber = iCheckNumber + 1;
                        //sw.WriteLine("COMMENT: CHECK NUMBER # {0}", iCheckNumber);
