You can build an expression tree which contains an equality comparison using
Expression.Equal 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 greaterThanExpr = Expression.Equal( Expression.Constant(31), Expression.Constant(31) ); Console.WriteLine(Expression.Lambda<Func<bool>>(greaterThanExpr).Compile()());
