Question

Trying to convert some VB to C#… (learning C#, too).
I have some code that loops through files in a directory and retrieves their file information. I have this originally in VB, but am trying to learn C#, and the online convertors don’t give me code that will pass .net 2.0.

Here is the error:
Type and identifier are both required in a foreach statement

Here is the code I have:

DirectoryInfo dirInfo = new DirectoryInfo(currentDir);
FileInfo[] files = null;
files = dirInfo.GetFiles();

FileInfo f = default(FileInfo);
foreach (f in files) {  ...
}

I tried putting foreach(FileInfo f... but it gives me a different error:
A local variable named 'f' cannot be declared in this scope because it would give a different meaning to 'f', which is already used in a 'parent or current' scope to denote something else

How do I fix it?

Answer 1

DirectoryInfo dirInfo = new DirectoryInfo(currentDir);
FileInfo[] files = null;
files = dirInfo.GetFiles();

// I removed the declaration of f here to prevent the name collision.
foreach (FileInfo f in files)
{  ...
}

Here is a simpler version of the code:

DirectoryInfo dirInfo = new DirectoryInfo(currentDir);
foreach (FileInfo f in dirInfo.GetFiles())
{
}
