InLogical  Conversion (Array to InLogical)

public static implicit operator InLogical (
	Array A
)

Public Shared Widening Operator CType ( 
	A As Array
) As InLogical

Dim input As Array
Dim output As InLogical

output = CType(input, InLogical)

Parameters

A

Type: SystemArray
System.Array of arbitrary size

Return Value

Elements of A will be converted to elements of the output array, where non-null elements (reference types) and '!= 0' values (value types) in A create 'true' values in the result. The following element types are supported for A: all IConvertible types (double, float, int, uint, long, ulong, short, ushort, sbyte, byte etc.), and reference types.

The resulting Array will reflect all dimensions of A. Due to the fact that .NET System.Arrays are stored in row major order the storage layout of the resulting Array will be RowMajor also. Elements of an one-dimensional A will be ordered along the first dimension of the result. Hence, one-dimensional input arrays will produce column vectors.

Convert is used for the conversion of elements in A to bool elements.

The current value of MinNumberOfArrayDimensions is considered. Its default value of 2 will cause a matrix to be produced, even though the input A may be a one-dimensional array.
