Expression Tree Tutorial GreaterThanOrEqual

You can build an expression tree which contains a "greater than or equal" numeric comparison using Expression.GreaterThanOrEqual method. For example, you have the following code.

bool value = 31 >= 31;
Console.WriteLine(value);

Here is the code that is required to build the same functionality using expression tree.

Expression expr = Expression.GreaterThanOrEqual(
    Expression.Constant(31),
    Expression.Constant(31)
);


Console.WriteLine(Expression.Lambda<Func<bool>>(expr).Compile()());
