NullableString.CompareOrdinal Method (NullableString, Int32, NullableString, Int32, Int32)

Compares substrings of the two specified NullableString structures ,without considering the local national language or culture.

public static int CompareOrdinal(
   NullableString a,
   int indexA,
   NullableString b,
   int indexB,
   int length
);

Parameters

a: A NullableString structure.
indexA: The position of the substring within a.
b: A NullableString structure.
indexB: The position of the substring within b.
length: The maximum number of characters in the substrings to compare.

Return Value

A 32-bit signed integer indicating the lexical relationship between the two comparands.

Value	Description
A negative integer	the substring in a is less than the substring in b.
Zero	the substring in a is equal to the substring in b.
A positive integer	the substring in a is greater than the substring in b. -or- b is Null.

Remarks

By definition, any NullableString, including the Empty string, compares greater than Null; and two Null compare equal to each other. indexA and indexB are zero-based. length cannot be negative. If length is zero, then zero is returned. The number of characters compared is the lesser of the length of a less indexA, the length of b less indexB, and length.

Exceptions

Exception Type	Condition
ArgumentOutOfRangeException	The sum of indexA and length is greater than a. -or- The sum of indexB and length is greater than b. -or- indexA, indexB or length is negative.
