C# Equivalent of above code -
Form frm = default(Form);
string formName = "frmNewForm";
frm = (Form)Assembly.GetEntryAssembly.CreateInstance(formName);

Converted using http://www.developerfusion.com/tools/convert/vb-to-csharp

Have you got any form in Assemblies?

In addition to Solution 1: you can use open-source ILSpy to convert the whole assembly; it will create a reverse-engineered project written in selected language, with great accuracy and quality of the generated code. Please see my past answers (they explain how to use it):
Code Interpretation, C# to VB.NET[^],
Need to convert vb code to c#[^],
FixedPage to ContentPage convert c# code into vb.net[^],
Source Code from a exe[^].

Please, read my comment to your comment.

The main problem is not "How to convert vb.net to c#?", but "how to use assemblies?"

Have a look here:
How to: Add or Remove References By Using the Add Reference Dialog Box[^]
Assemblies and the Global Assembly Cache (C# and Visual Basic)[^]
Assembly Class[^]

Very good point, which should come first, before "convert" (which is just a translation).
But of course even the translation can be needed sometimes.
And, of course, 5ed.

Two solutions -
1. If it is small code or few files you want to convert from VB to C# then there are many online converter available -
http://www.developerfusion.com/tools/convert/vb-to-csharp/[^]
http://converter.telerik.com/[^]
http://www.carlosag.net/tools/codetranslator/[^]

If you want to convert entire project from VB.NET to C# then you need a project converter -
http://www.developerfusion.com/tools/convert/bulk/[^]

Hope this helps.

Try giving full name of the form with namespace and assembly name.
