c# - 不能在C#ASP.NET中绑定(bind)多部分标识符“TextBox1.Text”？

我正在做一个训练实习项目；为了降低基础知识，我的处理程序目前明确禁止参数化和面向安全的编码。就是说，我的主页上有一个gridview，其中包含一个超链接字段，该链接将用户带到一个页面，用户可以在其中编辑文本框中的行数据。该行由“ ProductId”列显示，因为该行是自动递增的并且是唯一的。值显示完美，因此我知道查询字符串很好，但是当我尝试使用button事件进行更新时，出现一条错误消息，内容为

多部分标识符“ TextBox1.Text”无法绑定。

对于我所有的文本框。我的代码如下。我想念什么？这是我的第一个牛仔竞技表演，因此对于有经验的眼睛来说，它可能非常基础且显而易见。

最佳答案

您必须将Text控件的TextBox属性的值作为字符串传递给查询，而不是“ TextBox.Text”：

string updateQuery = "UPDATE ProductInstance SET CustId = " + TextBox1.Text + ", CustName = '" + TextBox2.Text + "', .... " + x;

注意：

如果“ Text”属性的值为字符串，则必须像上面的示例一样在该值的两侧放置一个'。
