c# - Value for html control always null

Question

I know I have a similar question but I selected a answer as correct before I actually tested it since technically they were correct I was trying to use .text.

I have html control and im trying to get the input value from the user however for some reason even though I have data when I debug that line it just shows ""

<input runat="server" id="Name" type="text" name="Name"/>

cmd.parameters.addwithvalue("@NAME", Name.value);

name.value never has a value no matter what I put in the input name control.

Answer 1

删除引号：

cmd.parameters.addwithvalue("@name", name.value);

您实际上是在传递“name.value”而不是 value 属性。

Answer 2

尝试这个

<input runat="server" id="Name" type="text" name="Name"/>

cmd.Parameters.Add(new SqlParameter("@name", name.value));

Answer 3

试试看

<input runat="server" id="Name" type="text" name="Name"/>

cmd.Parameters.Add(new SqlParameter("@name", Request.Form["Name"]));
