Answer 1

The smallest element you can check out with Subversion is a directory. It is not possible to check out a single file.
You can check out a directory, but leave it empty, via the Sparse Directories feature. Then update only the file you're interested in. But you must start with a directory.

FYI if you want to checkout empty use following syntax
//first define args
SvnCheckOutArgs args = new SvnCheckOutArgs();
// then for checkout only forlder empty
args.Depth = SvnDepth.Empty;
//checkout folder
client.CheckOut(url,txtLocalFilePath.Text.Trim(),args,out result)
