试试这个：

Hi,
Try this:

<iframe height="450px" width="450px" scrolling="auto" runat="server" id="iFrame1" />

protected void Page_Load(object sender, EventArgs e)
{
    string Url = "TXT/business applications_en.htm";
    //iFrame1.Attributes["src"] = Url;
    System.Web.UI.AttributeCollection aCol = iFrame1.Attributes;
    aCol.Add("src", "Test\test.aspx");
}

或



试试这个：添加一个隐藏的输入字段（使用runat =server属性）并将其值更改为JavaScript中的IFrame的src。这样，您就可以阅读该字段的值服务器端。

OR

Try this: add a hidden input field (with runat="server" attribute) and change it's value to your IFrame's src in the JavaScript. That way, you'll be able to read the field's value server-side.

ifrmMain.Attributes [src] =您的页面名称;

ifrmMain.Attributes["src"] = "Your page name";
