This topic compares the operators between Microsoft Dynamics AX X++ and C#.

Assignment Operators

The following table displays the differences between the assignment operators in X++ and C#.

X++ and C#	Differences
=	In X++ this operator causes an implicit conversion whenever a loss of precision might occur, such for an assignment from an int64 to an int. But in C# the assignment causes a compile error.
+= and -=	The only difference is that in C# these operators are also used in delegate manipulation.
++ and --	These are the increment and decrement operators in both languages. The following line is identical in both languages: ++myInteger; But in X++ these two operators are for statements, not for expressions. Therefore the following lines generate compile errors in X++: myStr = int2str(++myInteger); myIntA = myIntBB++;

X++ and C#

Differences

In X++ this operator causes an implicit conversion whenever a loss of precision might occur, such for an assignment from an int64 to an int. But in C# the assignment causes a compile error.

and

The only difference is that in C# these operators are also used in delegate manipulation.

and

These are the increment and decrement operators in both languages. The following line is identical in both languages:

++myInteger;

But in X++ these two operators are for statements, not for expressions. Therefore the following lines generate compile errors in X++:

myStr = int2str(++myInteger);
myIntA = myIntBB++;

Arithmetic Operators

The following table lists the arithmetic operators.

X++ and C#

Differences

As the multiplication operator, there are no differences.

Note

The asterisk is also used in the SQL statements that are part of the X++ language. In these SQL statements the asterisk can also be one of the following:

A wildcard indicating that all the columns should be returned.
A wildcard for characters in a string that is used on a like clause.

For more information, see Relational Operators.

The division operator is the same in X++ and C#.

MOD

For modulo operations, the only difference is that the % symbol is used in C#.

The addition operator is the same in X++ and C#. The plus sign is also used for string concatenation.

This operator adds numbers and concatenates strings in both languages.

The subtraction operator is the same in X++ and C#.

Bitwise Operators

The following table compares the bitwise operators between X++ and C#.

X++ and C#	Differences
<<	The left shift operator is the same in X++ and C#.
>>	The right shift operator is the same in X++ and C#.
~	The bitwise NOT operator is the same in X++ and C#.
&	The binary AND operator is the same in X++ and C#.
^	The binary XOR operator is the same in X++ and C#.
\|	The binary OR operator is the same in X++ and C#.

Relational Operators

The following relational operators are the same in X++ and C#:
