String.Split on VB.NET

I am trying to do a String.Split on VB.NET and it doesn't appear to work. Appreciate any help to see what I am missing:

In C#:

sFileContents = File.ReadAllText(f.FullName);
sLines = sFileContents.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);

In VB.NET:

sFileContents = File.ReadAllText(f.FullName)
sLines = sFileContents.Split(New String() {"\r\n"}, StringSplitOptions.RemoveEmptyEntries)

In C# I get the number of lines split correctly and in VB.NET I only get 1 line.

Thanks

Use this:

sFileContents = File.ReadAllText(f.FullName)
sLines = sFileContents.Split({ Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries)

Also, note that New String() is omitted in the code above. VB.NET can directly accept arrays in the form { <element>, <element> }. So no need for the New keyword and the initializer.

You should, in fact use Environment.NewLine as you can never be certain about line-endings on different platforms.

In VB.NET, "\r\n" is interpreted as "\r\n" itself and not a Carriage-Return + NewLine as with C#. They are called special characters. VB.NET doesn't have any. It's only the double quotes which need escaping (by using pairs). For Example:

Dim result = "He said, ""This is some code.""" 'Yields : He said, "This is some code."

Another option would be to use predefined VB.NET constants like vbCrLf but I would say that Environment.NewLine is a better way.

Escape sequences don't work in VB.NET.

You should use the VB.NET constants: vbCrLf, vbLf

sFileContents = File.ReadAllText(f.FullName)
Dim arg() As String = {vbCrLf, vbLf}
sLines = sFileContents.Split(arg, StringSplitOptions.RemoveEmptyEntries)
