What is the method for comparing strings in VB?
In VB, the method for comparing the size of strings is to use the Compare method of the string. It returns an integer value that represents the relative order of the two strings.
There are several methods of comparison available:
- Compare the differences using the Compare method.
Dim result As Integer = String.Compare(str1, str2)
If the value of “result” is 0, it means that str1 is equal to str2. If it is positive, str1 is greater than str2. If it is negative, str1 is less than str2.
- Compare using the CompareOrdinal method:
Dim result As Integer = String.CompareOrdinal(str1, str2)
The CompareOrdinal method compares strings as a series of Unicode characters, without considering the current culture settings and casing rules.
- Compare using the CompareTo method:
Dim result As Integer = str1.CompareTo(str2)
The CompareTo method is used to compare the size relationship between the current string and a specified string. It returns an integer value that indicates the relative order between the current string and the specified string.
These methods can compare based on the sensitivity to case, which can be set using the CompareOptions parameter.
