Code Conversion - Convert Vb Into C# ?

I want to convert this vb into c#, I cant correct it

Public Function encryptPassword(ByVal Password As String, ByVal Salt As String) As String
Using HashTool As New SHA512Managed()
Dim PasswordAsByte() As Byte = System.Text.Encoding.UTF8.GetBytes(String.Concat

[CODE]...

I was suggested this code:

public string encryptPassword(string Password, string Salt) {
Using;
((void)(HashTool));

[CODE]...

But it wasn't correct at all.
