              string DR = Request.QueryString["DR"].ToString();
              DR = DR.Replace(' ', '+');
              sQS = Base64Decode(DR);
              DR = RC4.Decrypt(pwd, sQS, false);

                  lsDetail1 += lsDetail2;
  
                  Response.Write(lsDetail1);
  
                  lsDetail1 = "";
  
                  lsDetail2 = "";

  Line 49:                 lsDetail1 += "<td align='left'>" + aParam[0] + "</td></br>";

  try

  if (aParam.Count()>1)
  {
  lsDetail1 = "<table align='center' width='600' cellpadding='2' cellspacing='2' border='0'>";
  lsDetail1 += "<td align='left'>" + aParam[0] + "</td></br>";
  lsDetail2 = "<td align='left' width='50%'>" + aParam[1] + "</td>";
  lsDetail2 += "</tr></table>";
  lsDetail1 += lsDetail2;

  Hi oned_gk

  oned_gk

  try

  if (aParam.Count()>1)
  {
  lsDetail1 = "<table align='center' width='600' cellpadding='2' cellspacing='2' border='0'>";
  lsDetail1 += "<td align='left'>" + aParam[0] + "</td></br>";
  lsDetail2 = "<td align='left' width='50%'>" + aParam[1] + "</td>";
  lsDetail2 += "</tr></table>";
  lsDetail1 += lsDetail2;
  Response.Write(lsDetail1);
  lsDetail1 = "";
  lsDetail2 = "";
  }

  I have tried with ur suggestion, now the result page is empty, not showing up anything.

  Few days back, I was able to recieve the response from payment gateway, do some backend insertion and finaly display the confirmation message to the user.

  The page used to execute fine with no problems of index out of bound issue, but suddenly how it has come now m not getting and where to check. 

  With some search on web, i found some other ways to resolve where it mentioned that 

  1. recylicng the application pool.

  I have tried that also, but still the same result.

  Any other suggestions from anyone would be helpful. 

  Thanks for your time.

  Hi All,

  I would like to add one more thing here. If i use breakpoint in the response page, it not getting step by step execution. If i am able to debug using step by step execution, then atleast i can have some idea of why it is giving such error.

  Thanks,

  Saleem

  It seems like you are having wrong value in "DR" [QueryString]

  check for the following cases

  i) may be some parameter is coming without value (e.g; value1=1&value2=&value3=3), Or

  ii) may be some parameter is containing "&" sign in it, like if you are passing name/text in values.

  both could break the algo of splitting the values.

  Please mark it as Answer, if it answers your question.

  the problem from here :

  string[] aParam = param.Split('=');

  
  
  I dont realy understand what you want with that.

  Spilted value not realy splitted.

  try

  string[] aParam = param.Split("="); 

  
  make sure you always get aParam[0] and aParam[1]

  Hi

  Thanks to both of you  for replying. i would definitely look into what you both have suggested. Meanwhile I would like to make apoint again that, the same code i ran on server without any problem.

  Now if it is giving this error, then is der something wrong from the payment gateway response?. because the code i am using has been provided the payment gateway itself in the integration kit. 

  please suggest.

  Thanks,

  Saleem
