// returns:
// "c:\MyDir\my-car.BMP"
// "c:\MyDir\my-house.jpg"

You can specify search pattern. You can use wildcard specifiers in the search pattern, e.g. „*.bmp“ to select files with the extension or „a*“ to select files beginning with letter „a“.

[C#]

string[] filePaths = Directory.GetFiles(@"c:\MyDir\", "*.bmp");
// returns:
// "c:\MyDir\my-car.BMP"

Get files from directory (including all subdirectories)

If you want to search also in subfolders use parameter SearchOption.AllDirectories.

[C#]

string[] filePaths = Directory.GetFiles(@"c:\MyDir\", "*.bmp",
                                         SearchOption.AllDirectories);
// returns:
// "c:\MyDir\my-car.BMP"
// "c:\MyDir\Friends\james.BMP"
