GetUpperBoundint

GetUpperBoundint is not a standard, widely adopted function in mainstream programming languages. It commonly appears as a non-standard or wrapper name used in some codebases to denote retrieving the upper bound of an array’s dimension and returning it as an integer. The canonical built-in method for this purpose in many environments is Array.GetUpperBound, which returns the upper index of a specified dimension for a given array.

In .NET, the method signature is GetUpperBound(dimension As Integer) As Integer. It is called on an array object and returns the inclusive upper bound for the given dimension. For example, in a one-dimensional array declared as Dim a(4) As Integer, a.GetUpperBound(0) returns 4. For a two-dimensional array like Dim m(2, 5) As Integer, m.GetUpperBound(0) returns 2 and m.GetUpperBound(1) returns 5. The corresponding lower bound can be retrieved with GetLowerBound, and the total length of a dimension with GetLength.

If a function named GetUpperBoundint appears in a codebase, it is typically a wrapper or alias around the standard GetUpperBound method, often returning the value as an Integer type (int) or providing a naming convention used by the project. Implementations may look like a simple pass-through, e.g., a function GetUpperBoundint(arr As Array, dim As Integer) As Integer = arr.GetUpperBound(dim).

Notes: array bounds are language- and platform-dependent. Some languages (like C#) expose length rather than explicit lower bounds, while VB-derived environments provide both GetUpperBound and GetLowerBound for compatibility with older VB concepts.
