Expression Tree Tutorial DivideAssign
You can build an expression tree which contains a division assignment operation using Expression.DivideAssign method. For example, you have the following code.
int myInt; myInt = 60; myInt /= 5; Console.WriteLine(myInt);
Here is the code that is required to build the same functionality using expression tree.
ParameterExpression myIntVariableExpr = Expression.Variable(typeof(int), "myInt"); BlockExpression addAssignExpr = Expression.Block( new ParameterExpression[] { myIntVariableExpr }, Expression.Assign(myIntVariableExpr, Expression.Constant(60)), Expression.DivideAssign( myIntVariableExpr, Expression.Constant(5) ) ); Console.WriteLine(Expression.Lambda<Func<int>>(addAssignExpr).Compile()());
