Jak przetłumaczyć kod - Invoke z VB.NET na C#?

    Public Delegate Function pobierz_delegat(parameters As String, linijka As Integer) As String

    Private Function pobierz(parameters As String, linijka As Integer) As String
        If InvokeRequired Then
            Return (Me.Invoke(New pobierz_delegat(AddressOf pobierz), parameters, linijka))

   public delegate string pobierz_delegat(string parameters, int linijka);
            if (InvokeRequired)
            {

public delegate string pobierz_delegat(string parameters; int linijka);

private string pobierz(string parameters; int linijka)
{
    if(this.InvokeRequired)
    {
        // jakiś kod
    }
}
