我有网格视图，其中我想用复选框选择多行，我想删除那些行，但它显示错误

这里的代码请帮帮我

 protected void btnDelete_Click（object sender，EventArgs e）
 {
 
 foreach（GridViewRow gvrow in Grid.Rows）
 {
 
 CheckBox chkdelete =（CheckBox）gvrow.FindControl（chkdelete）; 
 
 if（chkdelete.Checked）
 {
 int usrid = Convert.ToInt32（Grid.DataKeys [gvrow.RowIndex] .Value.ToString（））; 
 objUsers.DeleteParameters [Id]。DefaultValue = usrid.ToString（）; 
 objUsers.Delete（）; 
 
 
 BindEmployeeDetails（）;
