IExpression expression = new Expression(); expression.AddOperand(2); expression.AddOperand(3); expression.AddOperand(4);
IExpression expression = new Expression(); expression.AddOperand(5); expression.AddOperand(2); expression.AddOperand(1); IExpression subExpression = new Expression(); subExpression.AddOperand(3); subExpression.AddOperand(1); expression.AddOperand(subExpression);In this example, we create an expression object and add three operands to it (5, 2, and 1). We then create a sub-expression object and add two operands to it (3 and 1). Finally, we add the sub-expression to the original expression as an operand. This could be used in a program to perform a subtraction operation (5 - 2 - 1 - (3 - 1) = 0). The package library for the IExpression AddOperand method is likely the System.Linq.Expressions namespace, which is used to define expression trees that can be used to represent code as data.
