String vs string [duplicate]

Answer 1

There is no difference. string (lower case) is just an alias for System.String.

Answer 2

There is no difference between them. string is just an alias for System.String. When compiled they both are compiled to System.String object.

Answer 3

In the future, try compiling an app that uses both and then use Reflector (change the language to IL) to view the compiled output. You'll see there's no difference.

Answer 4

No difference. System.String is strictly identical to string. Common C# coding guidelines indicates that you should use the keyword string.

Answer 5

One is System.String the .Net Type and one is specific to C# which turns out to be an alias back to System.String.

Answer 6

There is no difference because string is converted to System.String by the compiler. Same with all of the common types (int goes to System.Int32, etc). We use the simple name so they stand out.
