C# check directory path exists

Question

In a C# 2008 application, I have a check to make certain the directory file does not exist. if it does not exist, then I want to display an error message. 

Here is the code I have so far:

string strFullpath = '"C:\\Data\\IFiles"

if (!Directory.Exists(strFullpath))

{

display error message

}

else

{

}

The code is not correct somehow. The directory file does exist. Thus can you tell me how to change this code to really check if the directory file does exist?
