The following XLANG/s operators are available for use in orchestration expressions. They adhere closely to the functionality of the corresponding operators in C#.
| Operator | Description | Example |
|---|---|---|
| checked() | raise error on arithmetic overflow | checked(x = y * 1000) |
| unchecked() | ignore arithmetic overflow | unchecked(x = y * 1000) |
| new | create an instance of a class | myObject = new MyClass; |
| typeof | Type retrieval | myMapType = typeof(myMap) |
| succeeded() | test for successful completion of transactional scope or orchestration | succeeded(<transaction ID for child transaction of current scope or service>) |
| exists | test for the existence of a message context property | BTS.RetryCount exists Message_In |
| + | unary plus | +(int x) |
| - | unary minus | -(int x) |
| ! | logical negation | !myBool |
| ~ | bitwise complement | x = ~y |
| () | cast | (bool) myInt |
| * | times | Weight = MyMsg.numOrders * 20 |
| / | divided by | x / y |
| + | plus | x + y |
| - | minus | x - y |
| << | shift left | x << 2 |
| >> | shift right | x >> 2 |
| < | less than | If (MyMsg.numOrders < 10)... |
| > | greater than | If (MyMsg.numOrders > 10)... |
| <= | less than or equal to | If (MyMsg.numOrders <= 10)... |
| >= | greater than or equal to | If (MyMsg.numOrders >= 10)... |
| == | equal to | If (MyMsg.numOrders == 10)... |
| != | not equal to | If (MyMsg.numOrders != 10)... |
| & | and | If (myByte & 255)... |
| ^ | exclusive or | If (myByte ^ 1)... |
| | | or | If (myByte | 1)... |
| && | conditional and | If (MyMsg.numOrders > 10) && (MyMsg.numOrders < 100) |
| || | conditional or | If (MyMsg.numOrders < 10) || (MyMsg.numOrders > 100) |
| // | commenting | //This is the comment |
Note
The rules differ between general expressions and filter expressions that are used with the Receive shape.
