Question

我想添加一个Url参数。

例如：http://localhost:65319/Example.aspx?FirstName=value

这是我目前的代码

Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles SearchButton.Click
        Dim dt As New DataTable
        Using con As New OdbcConnection("DRIVER={SQL Server};Server=WJNJPHR8TCX8P\SQLEXPRESS;Database=Fabrics;Integrated Security=True;"),
          cmd As New OdbcCommand("SELECT * FROM [Client] WHERE OR [FirstName] = ?", con)
               con.Open()

           cmd.Parameters.Add("@FirstName", OdbcType.NVarChar).Value = FNameTextBox.Text

           dt.Load(cmd.ExecuteReader())
           End Using

           GridView1.DataSourceID = Nothing
           GridView1.DataSource = dt
           GridView1.DataBind()

End Sub

您可以咨询MSDN- How to: Pass Values Between ASP.NET Web Forms Pages

您可以查看查询字符串部分并执行以下操作：

 cmd.Parameters.Add("@FirstName", OdbcType.NVarChar).Value = Request.QueryString("FirstName")

甚至更好，添加一些验证以确保填充FirstName：

If Not Request.QueryString("FirstName") Is Nothing Then
      cmd.Parameters.Add("@FirstName", OdbcType.NVarChar).Value = Request.QueryString("FirstName")
Else
      ????
End If
