参数名称:index

Index was out of range. Must be non-negative and less than the size of the collection.

string query = "update Questionnaire_UserAnswers set Comments='" + grdView.Rows[].Cells[1].Controls[0] + "', Marks=" + grdView.Rows[4].Cells[5].Controls[0] + " where Question_ID=" + grdView.Rows[0].Cells[1].Controls[0] + "UserName='" + Request.QueryString["UserName"] + "'";

请纠正此错误

Please Rectify this Error

推荐答案

检查是否未在gridView1.Rows []中为第一个值提供索引:

check once u are not provided index in gridView1.Rows[] at first value:

grdView.Rows[].Cells[1].Controls[0] 

提供行索引

provide row index

好，这意味着您使用的索引器之一超出了数组长度.
请确保:
1-您的grView至少有5行.
2-您的grView至少有6列.
3-您的第2列和第6列中已经至少包含1个控件.

Well,this means that one of the indexer you are using exceeded the array length.
Make sure that:
1- Your grView have at least 5 rows.
2- Your grView has at least 6 columns.
3- Your 2nd and 6th columns already have at least 1 control in it.
