Determines length of the longest common prefix of the current browse path and a given browse path.
Syntax
'Declaration
<PureAttribute()>
Public Function CommonPrefixLength( _
ByVal As BrowsePath _
) As Integer
'Usage
Dim instance As BrowsePath
Dim path2 As BrowsePath
Dim value As Integer
value = instance.CommonPrefixLength(path2)
Parameters
- path2
- The other browse path.
Because the BrowsePath has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (containing an absolute browse path to be parsed) in place of this parameter, and the corresponding browse path object will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromString static method instead. CAUTION: Parsing the browse path can throw OpcLabs.BaseLib.Navigation.Parsing.BrowsePathFormatException.
The value of this parameter cannot be null (Nothing in Visual Basic).
Return Value
The common prefix length. Zero if there is no common prefix.
Exceptions

| System.ArgumentNullException |
A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.
This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception. |
