Question

我有这个网址（mydomain.com/mypage.aspx）。我想获取文件名＆＃34; mypage＆＃34;只在网络方法中。我尝试了以下代码，但我只获得了函数本身的名称（MyMethod）。我没有从网址获取该网页的名称。任何帮助都很受欢迎。

修改更具体地说，webmethod驻留在用户控件中，因此使用FilePath OR PhysicalPath会在URL中为我提供UserControl文件名（MyUserControl）的名称，而不是aspx页面（mypage）。

mypage.aspx

<asp:Content ID="Content" ContentPlaceHolderID="ContentPlaceHolder" runat="server">
<uc:myUserControl runat="server" /> 
</asp:content>

myUserControl.cs

public static string PageName { get { 
    return (string)(Path.GetFileNameWithoutExtension(
        Convert.ToString(HttpContext.Current.Request.Url)));
} }

OR

public static string PageName { get {
    return (string)(Path.GetFileNameWithoutExtension(
        HttpContext.Current.Request.RawUrl));
} }

OR

public static string PageName { get {
    return (string)(Path.GetFileNameWithoutExtension(
        HttpContext.Current.Request.PhysicalPath));
} }

[WebMethod]
public static string MyMethod()
{
    StringBuilder SBstring = new StringBuilder();
    SBstring.Append(PageName);
    return SBstring.ToString();
}

只需像这样使用FilePath：

        var fi = new FileInfo(HttpContext.Current.Request.FilePath);
        var fileNameWithoutExtension = Path.GetFileNameWithoutExtension(fi.Name);
