Many a times we need the application path of the clickonce installed application. From the APIs we can get the datadirectory, usually is
C:\Documents and Settings\\Local Settings\Apps\2.0\Data\ \ \ _ \Data
But you want
C:\Documents and Settings\\Local Settings\Apps\2.0\ \ \ _
truncatedappname is the first four letters of the application name and with 2 dots and the last 4 letters of the application.
So, here is the hack to get the actual path of the app.
private string GetApplicationPath()
{
string strDataDirectory = ApplicationDeployment.CurrentDeployment.DataDirectory.ToString();
string truncatedappname = "myap..tion";
string strRoot = strDataDirectory.Substring(0, strDataDirectory.IndexOf("2.0") 4);
string strLastFolder = strDataDirectory.Substring(strDataDirectory.IndexOf(truncatedappname));
strLastFolder = strLastFolder.Substring(0, strLastFolder.Length – 5);
DirectoryInfo dirFirst = new DirectoryInfo(strRoot);
DirectoryInfo[] subdirectories = dirFirst.GetDirectories();
foreach (DirectoryInfo dirSecond in subdirectories)
{
DirectoryInfo[] subdirectories2 = dirSecond.GetDirectories();
foreach (DirectoryInfo dirThird in subdirectories2)
{
DirectoryInfo[] subdirectories3 = dirThird.GetDirectories();
foreach (DirectoryInfo dirForth in subdirectories3)
{
if (dirForth.Name == strLastFolder)
return (strRoot dirSecond.Name "\\" dirThird.Name "\\" strLastFolder "\\");
}
}
}
}
