如何将一个文本文件读入数据库的ntext字段？？如何将数据库的ntext字段写入文本文件？？

最好有代码实现。

[rgbcn]

string sfile1=Server.MapPath("intro/a.txt");
StreamReader Sr1= new StreamReader((sfile1),Encoding.Default);
string ReadFile1=Sr1.ReadToEnd();
try{
ReadFile1 = ReadFile1.Replace(" "," ");
textbox1.Text+=ReadFile1;
Sr1.Close();

读出来，用个变量存也可以了，然后写入数据库

FileInfo fi = new FileInfo(HttpContext.Current.Server.MapPath("Counter.txt"));
StreamWriter sw = fi.CreateText();
sw.WriteLine(counter.ToString());
sw.Flush();
sw.Close();
