请问如何在程序中动态设置<PARAM NAME="Filename" VALUE="这里是要播放的媒体文件名">这句的文件名(最好是C#代码)

Answer 1

<PARAM NAME="FID="Filename" runat="server" VALUE="这里是要播放的媒体文件名">
</PARAM>设计器会给你警告：“PARAM不需要结束标记”，不要理会它！
然后在代码中（class域）声明：
protected HtmlGenericControl Filename;在过程中赋值：
Filename.Attribute.Add("VALUE","这里是要播放的媒体文件名_新文件名");

Answer 2

<PARAM NAME="Filename" ID="Filename" runat="server" VALUE="这里是要播放的媒体文件名">
</PARAM>

Answer 3

Filename.Attribute.Add("VALUE","这里是要播放的媒体文件名_新文件名");
这句编译时显示:
c:\inetpub\wwwroot\c_Learn\WebForm79.aspx.cs(25): “System.Web.UI.HtmlControls.HtmlGenericControl”并不包含对“Attribute”的定义
请问如何修改?

Answer 4

楼主写错了吧,应该是
Filename.Attributes.Add("VALUE","这里是要播放的媒体文件名_新文件名");
少加了一个s

Answer 5

Filename.Attributes.Add("VALUE","这里是要播放的媒体文件名_新文件名");
请这句是在JavaScript中，不是在C#中？
请给出具体代码。
谢谢！

Answer 6

Filename.Attributes.Add("VALUE","这里是要播放的媒体文件名_新文件名");
请这句是在JavaScript中，不是在C#中？
请给出具体代码。
谢谢！????????
为什么说是javascript代码
本来就是cs代码

Answer 7

Filename.Attributes.Add("VALUE","这里是要播放的媒体文件名_新文件名");
在C#中编译时出现如下错误,请指导:
C:\Inetpub\wwwroot\c_Learn\WebForm77.aspx.cs(53): 找不到类型或命名空间名称“FileName”(是否缺少 using 指令或程序集引用？)

Answer 8

你在代码里面添加下面这一行了么？
protected HtmlGenericControl Filename;同时<PARAM NAME="Filename" ID="Filename" runat="server" VALUE="这里是要播放的媒体文件名"></PARAM>
这里要添加runat=server，你加了么？sp1234(来去都是缘)贴的方法你好像没有仔细看啊！

Answer 9

在类里要加
protected HtmlGenericControl Filename;
