Here is my code. Please help me.

C#

string day = dataGridView1.Rows[0].Cells[0].Value.ToString();//DateTime.Now.DayOfWeek.ToString();

           dataGridView1.Rows[0].Cells[1].Value = (Convert.ToDateTime(day.ToString())).DayOfWeek.ToString();
           for (int i = 1; i < 10; i++)
           {



               DateTime dtd = Convert.ToDateTime(day).Date;
               dtd = dtd.AddDays(7);
               dataGridView1.Rows[i].Cells[0].Value = dtd;
               DateTime date = dtd;
               dataGridView1.Rows[i ].Cells[1].Value = (Convert.ToDateTime(date.ToString())).DayOfWeek.ToString();

           }
       }

I get "error=Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index".

Please help me.

Solution 2

mark merrens is right.

to prevent error you can add in for loop if condition:

C#

if (this.dataGridView1.RowCount == i)
   break; // or return;

I hope this will prevent exception but this is bad way.

Solution 1

It look like your count limit could be too high:

C#

i < 10

Reduce that to an appropriate amount and try again.

You could also pre-determine the number of rows you are likely to find and use that instead so that you don't need to hard code any limits.
