Supported syntax

The contents of a .csx file look similar to a C# file with the following differences:

• You do not need to create classes.

• Since there are no classes, there are no methods, properties, or fields. Instead, you can create top-level functions and call them from one of the defined AVEVA Real-Time System (RTS) Events. Most C# syntax (other than the exceptions listed here) is accepted inside of a function body.

• You can define variables within functions and parameters to functions.

• You can use a number of automatically included variables. See Automatically included variables for details.

• Certain common namespaces and references are included automatically. See Namespaces and References for details.

• Use the #r syntax to add a reference.

• Use the #load syntax to load another .csx file.
