一个稀奇的问题!!
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
if( ! this.IsPostBack)
{
System.IO.DirectoryInfo info=new DirectoryInfo(@ "E:\c#示例 ");
foreach(System.IO.FileInfo f in info.GetFiles( "*.cs "))
{
String name=f.FullName;
long size=f.Length;
string s= " <font size=2 color=red> "+ " <input type= 'button ' id= 'd ' onclick= 'alert( 'hello world '); ' value= ' "+size.ToString()+ " ' </input> ";
Response.Write(s+ " "+name+ " "+f.CreationTime+ " <font> <br> <div align= 'left '> <hr color=blue size=1 width= '50% ' > </div> ");
}
}
}
这段代码中的Button单击没有效果 ,我查看了HTML发现这样了一个问题，
<font size=2 color=red> <input type= 'button ' id= 'd ' onclick= 'alert( 'hello world '); ' value= '1334 ' </input> E:\c#示例\enum.cs 2007-4-2 11:31:15 <font> <br> <div align= 'left '> <hr color=blue size=1 width= '50% ' > </div> <font size=2 color=red> <input type= 'button ' id= 'd ' onclick= 'alert( 'hello world '); ' value= '370 ' </input> E:\c#示例\io.cs 2007-4-2 11:50:12 <font> <br> <div align= 'left '> <hr color=blue size=1 width= '50% ' > </div>

为什么显示是这样的?
