一个本地好的,服务器上坏的的问题.
1.   从   资源url   读取内容,再对内容进行分析组合成一个   strWant;
2.   读取   模板   内容.
3.   用准备好的   strwant   取代   模板中的指定内容.并将取代后的模板写入输出文件.

-------------------------------------
代码如下:

参数:   OutFileStr   =   "../analysis/outfile.htm ";
　　     InUrlStr       =   "http://community.csdn.net/Expert/PostNew.asp?room=5202 ";
-------------------------------------

private   void   BuildAnalysis(string   OutFileStr,   string   InUrlStr)
{
WebRequest   myWebRequest   =   WebRequest.Create(InUrlStr);  
WebResponse   myWebResponse   =   myWebRequest.GetResponse();  
Stream   ReceiveStream   =   myWebResponse.GetResponseStream();
Encoding   encode   =   System.Text.Encoding.GetEncoding( "gb2312 ");
StreamReader   readStream   =   new   StreamReader(   ReceiveStream,   encode   );

//   "../Analysis/AnalysisArticleTpl.htm "   是模板文件
FileStream   fsForTemplate   =   new   FileStream(Server.MapPath( "../Analysis/AnalysisArticleTpl.htm "),   FileMode.Open,   FileAccess.Read);
StreamReader   srForTemplate   =   new   StreamReader(fsForTemplate,   encode);
string   strTemplate   =   srForTemplate.ReadToEnd();
Char[]   read   =   new   Char[256];
int   count   =   readStream.Read(   read,   0,   256   );
StringBuilder   strhtml   =   new   StringBuilder( " ");
while   (count   >   0)
{
String   str   =   new   String(read,   0,   count);
strhtml.Append(str);
count   =   readStream.Read(read,   0,   256);
}
readStream.Close();
srForTemplate.Close();
fsForTemplate.Close();
//   Rsplay(stringbuilder)   是一个分析组合方法
Rsplay(strhtml);
FileStream   fs   =   new   FileStream(Server.MapPath(OutUrlStr),   FileMode.Create,   FileAccess.Write);
StreamWriter   writeStream   =   new   StreamWriter(fs,   encode);

//   MessageBox_Open(string)   用来弹出进行到的步骤,在这里,本地可以弹,服务器上不能弹出
//   模板,资源url试过了,可以读可以弹.
this.MessageBox_Open(Server.MapPath(OutUrlStr));
strTemplate   =   strTemplate.Replace( "{AnalysisArticle} ",   strhtml.ToString());
writeStream.Write(strTemplate);
writeStream.Close();
myWebResponse.Close();
}

OutFileStr在方法里没直接用，是不是和这个路径有关，查下
