Expression Tree Learn how to execute dynamic code at runtime using Expression Tree.

int num = 60;

var testCondition = Expression.Constant(num > 10);
var ifTrueBlock = WriteLineExpression("num is greater than 10");
var ifFalseBlock = WriteLineExpression("num is less than or equal to 10");

var ifThenElseExpr = Expression.IfThenElse(
    testCondition,
    ifTrueBlock,
    ifFalseBlock);

Expression.Lambda<Action>(ifThenElseExpr).Compile()();
