如何使用“保存”對話框創建和保存ics文件？

Question

我正在進行進度控制。 我需要導出計划約會。 從下面的代碼中，我已經在temp文件夾中創建了Test.ics文件，然后將其復制到新位置。

如何保存文件而不臨時保存在temp文件夾中。 是否可以將文件存儲在緩沖區或任何臨時對象中，而不是將其存儲在temp文件夾中？

請在下面找到我的代碼段...

string fileName = "Test.ics";
InternetCalendaring.ICSBuilder icsbBuilder = new InternetCalendaring.ICSBuilder(vecVEvents);
sRes = icsbBuilder.ICSBuildProcess();
string FilePath = System.IO.Path.GetTempPath() + fileName;
System.IO.File.WriteAllText(FilePath, sRes);
FileStream MyFileStream = new FileStream(FilePath, FileMode.Open);
long FileSize;
FileSize = MyFileStream.Length;
byte[] Buffer = new byte[(int)FileSize];
MyFileStream.Read(Buffer, 0, (int)MyFileStream.Length);
MyFileStream.Close();
System.Web.HttpContext.Current.Response.AddHeader("content-type", "text/Calendar");
System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);
System.Web.HttpContext.Current.Response.BinaryWrite(Buffer);
System.Web.HttpContext.Current.Response.Clear();
HttpContext.Current.Response.End();

提前致謝...

string fileName = "Test.ics";
InternetCalendaring.ICSBuilder icsbBuilder = new InternetCalendaring.ICSBuilder(vecVEvents);
sRes = icsbBuilder.ICSBuildProcess();

byte[] Buffer = Encoding.Unicode.GetBytes(sRes);

System.Web.HttpContext.Current.Response.AddHeader("content-type", "text/Calendar");
System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);
System.Web.HttpContext.Current.Response.BinaryWrite(Buffer);
//System.Web.HttpContext.Current.Response.Clear();
HttpContext.Current.Response.End();
