VB.Net vs C-Sharp

VB.Net vs C-Sharp Comparison is a very concise reference for commands you use every day. Print it out, hang it on the wall where it will not get lost, and use it every day.

Feature	Visual Basic .NET	Visual C# .NET
Case sensitive	Not case sensitive: response.write("Yo")  'OK	Case sensitive: response.write("Yo"); //Error Response.Write("Yo");  // OK
Functional blocks	Use beginning and ending statements to declare functional blocks of code: Sub Show(strX as String)   Response.Write(strX) End Sub	Use braces to declare functional blocks of code: void Show (string strX) { Response.Write(strX); }
Type conversion	Implicit type conversions are permitted by default: Dim intX As Integer intX = 3.14  ' Permitted You can limit conversions by including an Option Strict On statement at the beginning of modules	Type conversions are performed explicitly by casts: int intX; intX = 3.14; // Error! intX = (int)3.14; //Cast, OK Or, use type conversion methods: string strX; strX = intX.ToString();
Arrays	Array elements are specified using parentheses: arrFruit(1) = "Apple"	Array elements are specified using square brackets: arrFruit[1] = "Apple";
Methods	Statement termination Statements are terminated by carriage return: Response.Write("Hello")	Statements are terminated by the semicolon (;): Response.Write("Hello");
Statement continuation	Statements are continued using the underscore (_): intX = System.Math.Pi * _   intRadius	Statements continue until the semicolon (;) and can span multiple lines if needed: intX = System.Math.PI *    intRadius;
String operator	Use the ampersand (&) or plus sign (+) to join strings: strFruit = "Apples" & _   " Oranges"	Use the plus sign (+) to join strings: strFruit = "Apples" +    " Oranges";
Comparison operators	Use =, >, <, >=, <=, <> to compare values: If intX >= 5 Then	Use ==, >, <, >=, <=, != to compare values: if (intX >= 5)
Negation	Use the Not keyword to express logical negation: If Not IsPostBack Then	Use the ! operator to express logical negation: if (!IsPostBack)
Object comparison	Use the Is keyword to compare object variables: If objX Is objY Then	Use == to compare object variables: if (objX == objY)
Object existence	Use the Nothing keyword or the IsNothing function to check if an object exists: If IsNothing(objX) Then	Use the null keyword to check if an object exists: if (objX == null)
