点击按钮会出现加载数据的层,可是结束后报错:

你的Page_Load呢？？

在Page_Load中判断是否为回调

C# code
protected void Page_Load(object sender,EventArgs e)
{
if(!Page.IsPostBack){
//....
}
}

加了的

byte[] txtcontent = Encoding.Default.GetBytes(FileContent);
你这个是用字节读取到输入的吧，
我建议你用流来得到数据然后在转换过来，

文件下载-以字节流的形式下载





string    id=Request.QueryString["id"];   

string dbname;

string file;

string strSql="select Softname from Upload where Upload_ID="+id;



OleDbConnection conn=new OleDbConnection(); 

dbname=Server.MapPath"Data/cz.mdb");     

conn.ConnectionString="PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source="+dbname;



conn.Open();

OleDbDataAdapter ada=new OleDbDataAdapter(strSql,conn);

DataSet ds=new DataSet();

ada.Fill(ds);

conn.Close();   



file=ds.Tables[0].Rows[0][0].ToString();

FileInfo    thisfile=new    FileInfo(file);

string sFileName=thisfile.Name;

string filePath=Server.MapPath("DownFiles/")+file;

thisfile.Close();

              

Response.AppendHeader("Content-Disposition","attachment;filename="+HttpUtility.UrlEncode(sFileName,System.Text.Encoding.Default));//sFileName文件名   

Response.WriteFile(filePath);//filePath文件路径   

Response.End();
