C# String CompareOrdinal() Method
C# String CompareOrdinal()
CompareOrdinal() method compares the characters of two strings.
The characters of the strings may be in lower case or upper case, this method discriminates between them.
Every character holds an ASCII value (an integer ranging from 0 to 127). For example, 'A' holds the ASCII value of 65 and 'a' holds the ASCII value of 97. So, in the comparison between two strings, their ASCII values are compared.
CompareOrdinal() method starts comparison character by character starting from the first character until the characters in both strings are equal or a NULL character is encountered.
In the following example, the first character of str2 string object holds 'c' (ASCII value is 99) and the first character of str1 string object holds 'a' (ASCII value is 97). The
CompareOrdinal() method returns the difference in ASCII value i.e, 2.
|str2||Required||Specifies the string 2|
|str1||Required||Specifies the string 1|
|Number (int)||Returns the difference in ASCII value.|
