推荐答案

简单：不要试图将文本框传递给数据库：改为传递TextBox.Text属性。



很可能是你的代码包含一些参数化更新，并且您正在传递TextBox - 只需将.Text添加到TextBox名称的末尾，问题就会解决。

Simple: don't try to pass your Textbox to the database: pass the TextBox.Text property instead.

Chances are that your code contains some parametrized update, and you are passing the TextBox - just add ".Text" to the end of the TextBox name and the problem will go way.
