Tip - Get Files from Directory

From - csharp-examples.net



The method Directory.GetFiles returns string array with files names (full paths). For example:-





using System.IO;

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





Get files from directory (with specified extension)

You can specify a 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“.





using System.IO;

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.





using System.IO;

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