Open Multiple Document files from defined folder path using C# in ASP.Net

kavithav says:

System.Diagnostics.Process objDocProcess = new System.Diagnostics.Process();
 objDocProcess.EnableRaisingEvents = false;
 objDocProcess.StartInfo.FileName = Server.MapPath(@"OpenOfficeDoc\TestDoc.odt");
 objDocProcess.Start();

Change above with the below code.

System.Diagnostics.Process objDocProcess = new System.Diagnostics.Process();
objDocProcess.EnableRaisingEvents = false;
//objDocProcess.StartInfo.FileName = Server.MapPath(@"OpenOfficeDoc\TestDoc.odt");
DirectoryInfo directory = new DirectoryInfo(Server.MapPath(@"OpenOfficeDoc"));
FileInfo[] files = directory.GetFiles();
foreach (FileInfo file in files)
{
    string filePath = file.DirectoryName + "\\" + file.Name;
    if (filePath.Split('.')[filePath.Split('.').Length - 1].ToUpper() == "ODT")
    {
        objDocProcess.StartInfo.FileName = filePath;
        objDocProcess.Start();
    }
}
