如果您正在使用数据列表中的事件，则

If you are using in the datalist events then

Label Label1 = e.Item.FindControl("Label1") as Label;
string lblValue=Label1.Text;

除了数据列表事件

Other than datalist events

foreach (DataListItem dli in DataList1.Items)
            {
               Label Label1 = e.Item.FindControl("Label1") as Label;
               string lblValue=Label1.Text;
}

使用FindControl方法吗?

试试:

Using FindControl method?

Try:

//VB.NET
Dim lblId As Label = CType(Item.FindControl("lblId"),Label)

// C#
Label lblId = new Label();
lblId = (Item.FindControl("lblId")) as Label;

当我使用此标签时，出现应用程序文件中的错误，如预期的标识符

when i used this i get the error in application file like identifier expected
