That makes absolutely no fucking sense at all. You are confusing a lot of unrelated things.
.Net is not a programming language.
C# and VB.Net have similar capabilities but are not the same and the languages are fundamentally different.
C# is similar to the Java language, but closer to C++ than the Java language.
Many languages use the C style syntax, including Java. Java and C# are a long way from the C language.
.Net is similar to the Java platform but fundamentally contains more in many aspects.
You demonstrate a complete lack of understanding of the concets of Java, .Net and C.
