索引超出范围。必须为非负值并小于集合大小。
参数名: index

这是异常显示，一下是代码，如何解决？？？
//删除过程
protected void deletebtn_Click(object sender, EventArgs e)
{

try
{
int m;
for (m = 0; m <= gv.Rows.Count-1 ; m++)
{
CheckBox A = (CheckBox)gv.Rows[m].FindControl("CB");
if (A.Checked == true)
{
int y = Convert.ToInt32(gv.DataKeys[m].Value.ToString());
sbc.delete("deleteTypes", y);
}
}
Response.Write("<script>alert('删除成功！')</script>");

}
//catch (Exception)
//{
// Response.Write("<script>alert('删除失败！')</script>");

//}
finally
{
Dispose();
}
}

//对CheckBox类声明对象
CheckBox ck;
//创建SqlCommand类的对象
SqlCommand objSqlCommand = objsqlConnection.CreateCommand();
string sql = "delete from region where regionid=@id";
//用文本形式执行SQL语句
objSqlCommand.CommandText = sql;
objsqlConnection.Open();
//用for循环选中的项
for (int i = 0; i < GridView1.Rows.Count; i++)
{
//获取GrideView中的CheckBox1中的名字
ck = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (ck.Checked)
{
//将id设置为readonly获取id的值
int id = Convert.ToInt32(GridView1.Rows[i].Cells[0].Text);
//清空objSqlCommand对象中的参数
objSqlCommand.Parameters.Clear();
objSqlCommand.Parameters.AddWithValue("@id", id);
//执行SQL语句
objSqlCommand.ExecuteNonQuery();
}
}
//调用自定义方法
Bind();
