Solution 1

Apparently, it can happen when the number of rows is 0. You need to check for such cases before indexing a row.

the exception will be at line 436.

its always a good practice to check the table and row index before you operate on those variables. because at times you cannot guarantee it always returns the values as expected.

C#

if( dt6.Tables.Count >0 && dt6.Tables[0].Rows.Count > 0)
{  
 string amp5 = dt6.Tables[0].Rows[0][0].ToString();
}

Solution 3

Actually in this line you got this error message

C#

string amp5 = dt6.Tables[0].Rows[0][0].ToString();

In Row[0],there is no data that's way this error showing.
So, before that you check condition and then wrote this lines of code inside the If condition.

C#

if(dt6.Tables[0].Rows.Count>0)
{
    string amp5 = dt6.Tables[0].Rows[0][0].ToString();
}

It means, the table dt6 is not having any rows. It's a good practice to check for the null values firs before binding the values to the variables. Here is a sample I am writing. Try this and always check for the null values(Good Practice):

C#

System.Data.DataSet dt6 = new System.Data.DataSet();
da.Fill(dt6);
if(dt6!=null)
{
    if(dt6.Tables.Count > 0)
    {
        if(dt6.Tables[0].Rows.Count > 0)
        {
             if(dt6.Tables[0].Rows[0][0]!=DBNull.Value){
                  amp5 = dt6.Tables[0].Rows[0][0].ToString();
             }
        }
    }
}
