Using system classes

Scott Stewart

I am not sure if the title is even the correct use of the words system and classes. I was trying to write a function that looks for a specific file in a specific location. I added "using System.IO" to the directives and looking through the object browser I came across this;

"public override bool Exists { get; }
Member of System.IO.FileInfo

Summary:
Gets a value indicating whether a file exists.

Returns:
true if the file exists; false if the file does not exist or if the file is a directory."

Generally speaking, how can I use this? I started to try FileInfo.Exists @"c:\file path\ and name.and extension" but that wasn't accepted. All I want is to set a boolean if the file exists.

Thank you again.

Accepted answer
Rather than FileInfo, I'd use the File class which is easier to use for simple stuff as it contains nothing but static methods:

So here, you'd have:

if (File.Exists(@"c:\file path\ and name.and extension"))
{
// do something with file
}
else
{
MessageBox.Show("File does not exist");
}
