错误说明:无法将类型为"System.Web.UI.WebControls.GridViewRow"的对象转换为类型为"System.Web.UI.WebControls.GridView"的对象.

推荐答案

您的例外是告诉您出了什么问题.
您需要在for循环中使用GridViewRow而不是GridView:foreach(grdClient.Rows中的GridViewRow行)

grdClient.Rows是GridViewRow对象的集合.在此处检查

Hi,

Your exception is telling you whats wrong.
You need to use GridViewRow Not GridView in for loop: foreach (GridViewRow row in grdClient.Rows)

grdClient.Rows is a collection of GridViewRow objects. Check here[^].

foreach (GridView row in grdClient.Rows)

检查一下:

Check it:

foreach (GridViewRow row in grdClient.Rows)
