私の質問を参照して、ファイルの読み取り中に正しく実行していますか?
このコードを使用して iCal ファイルを作成していますが、正しく行っているのか、このエラーが発生したときに何かを処分する必要があるのか わかりません。
System.IO.IOException: The process cannot access the file 'C:\doc.ics' because it is being used by another process.

私が使用しているコードは、
String filePath = paramUri.LocalPath.ToString().TrimStart("filePath:///".ToCharArray());
int lastSlash = filePath.LastIndexOf('\\');
if(lastSlash > 0)
{
String folderPath = filePath.Substring(0, lastSlash);
DirectoryInfo di = new DirectoryInfo(folderPath);
if(!di.Exists)
di.Create();
}
//Use a streamwriter to create a file in the location specified in the URI
using (StreamWriter sw = new StreamWriter(filePath))
{
//Autoflush enabled so we don't have to worry about closing the streamwriter
sw.AutoFlush = true;
sw.WriteLine("BEGIN:VCALENDAR");
sw.WriteLine("PRODID:-//Microsoft Corporation//Outlook 12.0 MIMEDIR//EN");
sw.WriteLine("VERSION:2.0");
sw.WriteLine("METHOD:PUBLISH");
sw.WriteLine("X-MS-OLK-FORCEINSPECTOROPEN:TRUE");
//I am adding more details but they are not relevant to post
