Question

I have text files located in a directory. The text files are ordered by name in that directory. I want to read the paths of those text files with same order (by name) into array. I’m using the following code :

string[] textpaths = Directory.GetFiles(filepath + "\\source", "*",    
SearchOption.AllDirectories);  

But the array of paths I got doesn’t has the same directory order. Could any one help please?
Thanks in advance.

In which order, you can always sort the files using simple linq queries.

string[] textpaths = Directory.GetFiles(filepath + "\\source", "*",    
SearchOption.AllDirectories).OrderBy(x=>x).ToArray();  

Alternatively you can you DiretoryInfo.GetFiles to sort it using other attributes.

// Sort by full name  
string[] textpaths = new DirectoryInfo("c:\\test").GetFiles("*",    
SearchOption.AllDirectories).OrderBy(x=>x.FullName).Select(x=>x.FullName).ToArray();  

// Sort by creation time  
string[] textpaths = new DirectoryInfo("c:\\test").GetFiles("*",    
SearchOption.AllDirectories).OrderBy(x=>x.CreationTime).Select(x=>x.FullName).ToArray();
