怎样将数据输出到文件中

Question

卧室那样的，但总是出错：Stream filestream;
StreamWriter write;
.........
.........try
    {
      filestream=File.Create   
(d:\Inetpub\wwwroot\UltraEdit\guestsave.tmp);
     }            catch(DirectoryNotFoundExption e)
           {
            Console.WriteLine("path invalid");
           }
write=new StreamWriter(filestream);
           try
           { 
            write.WriteLine();
           write.Write(n+" on "+hostip+"("+hostname+")"+",you right is No."+right);
           write.Write("and error is No."+error+" ");
           write.WriteLine("正确率:{0:##.##}%",right/(double)(right+error)*100);
           }
           catch(IOExption e)
           {
            Console("data can't write");
           }

Answer 1

“流”在最后“关”了没有？？
close()啊？

Answer 2

public FuncReturn CommonDataWrite ( CommonData cd )
{
IsolatedStorageFile isf;
try
{
//获取和组合隔离的隔离存储
isf = IsolatedStorageFile.GetUserStoreForAssembly ();
}
catch( Exception err )
{
fr.Descibe = err.Message;
fr.Value = err.GetHashCode ();
return fr;
}
StreamWriter sw = null;
try
{
//构造流对象
IsolatedStorageFileStream isfStream = new 
IsolatedStorageFileStream( "MyBankWebServiceConfig.ini",FileMode.OpenOrCreate,FileAccess.Write,isf);
// 使用文件流构造文本写入流
sw = new StreamWriter(isfStream,System.Text.Encoding.Unicode );
//写入 cd 中的属性
sw.WriteLine ( "[DbName]" );//写入标签
sw.WriteLine ( cd.DataBase );
sw.WriteLine ("");//分行
sw.WriteLine ( "[DbPwd]" );//写入标签
sw.WriteLine ( cd.DbPwd );
sw.WriteLine ("");//分行
sw.WriteLine ( "[DbServer]" );//写入标签
sw.WriteLine ( cd.DbServer );
sw.WriteLine ("");//分行
sw.WriteLine ( "[DbUser]" );//写入标签
sw.WriteLine ( cd.DbUid );
fr.Value = 1;
return fr;
}
catch( Exception err )
{
fr.Descibe = err.Message;
fr.Value = err.GetHashCode ();
return fr;
}
finally
{
if ( sw != null )
{
//关闭流
sw.Close();
}
}
}
