Returns the lowest available subscript for the indicated dimension of an array.
Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)
- Type: System.Array
Required. Array of any data type. The array in which you want to find the lowest possible subscript of a dimension.
- Type: System.Int32
Optional. Integer. The dimension for which the lowest possible subscript is to be returned. Use 1 for the first dimension, 2 for the second, and so on. If Rank is omitted, 1 is assumed.
Return ValueType: System.Int32
Integer. The lowest value the subscript for the specified dimension can contain. LBound always returns 0 as long as Array has been initialized, even if it has no elements, for example if it is a zero-length string. If Array is Nothing, LBound throws an ArgumentNullException.
The following example uses the LBound function to determine the lowest available subscript for the indicated dimension of an array.
