Description
Create/use .NET objects and call instance/static method and get/set properties.
Sputnik is made in C# and C# is a .NET language.
Sputnik keeps all the .NET stuff hidden away and out of view and provides its own functions and features for you to use.
However if you wish to use something from .NET Sputnik has a special operator that lets you do that.
You can use the % operator with an Identifier to specify the creation/use of a .NET class see the examples below.
Remarks
To use .NET stuff you must first define where the object in question can be found in .NET you do that using the use() function.
Then you can create the object using the % opeator.
Note - When you use strings it uses Sputnik escapes and not C#/.NET ones (Which is fine since Sputnik has them all anyway and a lot more).
Example
Example of using .NETs Console.WriteLine() function
use("System"); %Console->WriteLine("Hello World!"); // Prints: Hello World!
Example of using .NETs StringBuilder class
use("System"); use("System.Text"); //$sb = %StringBuilder->new(100); // We could pre-allocate $sb = %StringBuilder->new(); $sb->Append("Cat"); $sb->Append("Dog"); %Console->WriteLine("StringBuilder Text: " . $sb); %Console->WriteLine("StringBuilder Length: " . $sb->$Length); // Prints: // StringBuilder Text: CatDog // StringBuilder Length: 6 // Now lets edit it $sb[0] = 'P'; say("Character 0 = " . $sb[0]); say("Character 3 = " . $sb[3]); %Console->WriteLine("StringBuilder Text: " . $sb); %Console->WriteLine("StringBuilder Length: " . $sb->$Length); // Prints // Character 0 = P // Character 3 = D // StringBuilder Text: PatDog // StringBuilder Length: 6
Example of using .NETs Static Environment class
use("System"); $CurDir = %Environment->$CurrentDirectory; echo "CurDir is: $CurDir\n";
Example of using .NETs String
use("System"); $str = %String->new("Hello"); // Sputnik will convert "" to char[] if needed printf("Char 0 is: %s\n", $str[0]); say("String value is " . $str); say("StringLen value is " . $str->$Length); $substr = $str->Substring(1); say("String value (with substring(1)) is $substr"); // Prints // Char 0 is: H // String value is Hello // StringLen value is 5 // String value (with substring(1)) is ello // Lets try a different creation type $str = %String->new('T', 20); say("String value is " . $str); say("StringLen value is " . $str->$Length); // Prints // String value is TTTTTTTTTTTTTTTTTTTT // StringLen value is 20
