C# and VB.NET

CSharp and VB.NET are the two primary languages used to program on the .NET Framework environment. Both languages are use the same framework and they both precompiled into the same byte code and then it is compiled and run at runtime. So we can say VB.NET and C# are functionally equivalent. Both C# and Visual Basic.NET share structural similarities with other modern high level languages such as Java and C++ .
But both have different in many features. Primarily keywords are different in each other language . C# is case sensitive while Visual Basic .NET is not. In VB.NET "Example" and "example" are same , but in CSHARP "Example" and "example" are two different variable names. Also it is good to remember that C# statements always terminated by a semicolon (;).
The following are some examples of differences between VB.NET and C#.

Single Line Comments :

VB.NET : ' ex: 'This is a single line comment
CSHARP : // ex: //This is a single line comment

Multi Line Comments :

VB.NET : Not available
CSHARP : /*..*/ ex: /*Multi line comments */

Conditional Statements

VB.NET

If condition Then
   'vb.net code
  Else
   'vb.net code
End If

CSHARP

if(condition)
  {
   //csharp code
  }
  else
  {
   //csharp code
}

Loops

VB.NET

For counter As Integer = 0 To final
   'vb.net code
Next

CSHARP

for(int i=0;i < final;i++)
  {
   //csharp code
}

Operator (Equal)

VB.NET

  a=b

CSHARP

  a==b;

Declaration

VB.NET

  Dim i as Integer = 10

CSHARP

  int i=10;
