public void ProcessRequest(HttpContext context)

file.SaveAs(fname);
}
}
context.Response.ContentType = "text/plain";
context.Response.Write("File/s uploaded successfully!");
}
C# 后台保存方法
public void SaveFile()
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>search();</script>");
string fileText = this.hdText.Value;
string[] fileArr = fileText.Split('$');
foreach (var item in fileArr)
{
if (!string.IsNullOrEmpty(item))
{
string[] filetext = item.Split(',');
if (filetext.Length==3)
{
if (filetext[0].Substring(0,2)=="20")
{
InsertAttachment(filetext[0], ModuleID, InfoID, filetext[1], "", DateTime.Now, ((PageBase)Page).CurrentUser.EmployeeID, 0, filetext[1], Path.GetExtension(filetext[1]),filetext[2].ToString().Replace("MB", "") );
}
}
}
