Parameters

strA

The first string to compare.

strB

The second string to compare.

Returns

An integer that indicates the lexical relationship between the two comparands.

Less than zero	strA is less than strB.
Zero	strA and strB are equal.
Greater than zero	strA is greater than strB.

Remarks

This method performs a case-sensitive comparison using ordinal sort rules. For more information about word, string, and ordinal sorts, see System.Globalization.CompareOptions. To perform a case-insensitive comparison using ordinal sort rules, call the string.Compare(string, string, StringComparison) method with a StringComparison value of StringComparison.OrdinalIgnoreCase.

Because string.CompareOrdinal(string, string) is a static method, strA and strB can be null. If both values are null, the method returns 0 (zero), which indicates that strA and strB are equal. If only one of the values is null, the method considers the non-null value to be greater.
