Framework Fundamentals - String - Comparing Strings

• In comparing two values, the .NET Framework differentiates the concepts of equality comparison and order comparison.
• Equality comparison tests whether two instances are semantically the same.
• Order comparison tests which of two (if any) instances comes first when arranging them in ascending or descending sequence.
• For string Equality comparison, you can use the
• == Operator
• string.Equals() static method as will as instance method, this option is better because they allow you to specify options such as case-sentitvity/culture-sensitivity.
• For string Order comparison, you can use the
• CompareTo() instance method
• string.Compare() static method
• stirng.CompareOrdinal() static method
• The return values of above said methods will be
• 0 for equal
• 1 if first value comes before second value
• 2 if second value comes before first value
•
