推荐答案

您需要将代码更改为此:

Hi,

You need to change your code into this:

SqlDataAdapter da = new SqlDataAdapter("Select CustName from offsale.OS_forsalelogin where email='" + (Session["user1"] = textName.Text.ToString()) + "'", util.sql_con);

提示也:
我认为textName是一个文本框，因此变量Text已经是一个string.因此，您无需调用ToString方法.

希望这会有所帮助.

A tip also:
I think textName is a text box, so the variable Text is a string already. So, you don''t need to invoke the ToString method.

Hope this helps.
