Silverlight file path separator issue

Question

Hello everyone,

I find when reading from a local file from Silverlight, we have to use special path separator "/" other than normal path separator "\" or else Silverlight can not get related local file, for example we need to write as c:/test/abc.wmv, other than write as c:\test\abc.wmv.

Two more questions,

1. Any simple solution to use normal file separator?

2. C# File/FileInfo class will use normal path separator to represent a file name (full path name), how to change all the normal path separator into this special path separator so that Silverlight could recognize?

I am using VSTS 2008 + C# + .Net 2.0.

thanks in advance, George

You could use an Extension Method:

public string ToSilverlightPath(this string s)
{
  return s.Replace("\\", "/");
}

or

public string ToSilverlightPath(this Path p)
{
  return p.GetFullPath().Replace("\\", "/");
}

Edit:

After thinking about it some more Silverlight probably works with URIs'.
That is, all paths in Silverlight are URIs'.
So instead of using Path you should probably use Uri, like:

Uri mySilverlightPath = new Uri(myPathString);

or

Uri mySilverlightPath = new Uri(myPath.GetFullPath());

Not sure about this though but I guess it would make sense.
