# AddColumns(Int32, Int32) Method

Create an 2-dimensional array of columns. This function returns a builder that generates columns according to a specification. The specification can be modified. In order to actually create the columns and get their indices, you have to call the returned builder's ToArray() function.
C#

    // Create a multi-dimensional array of binary columns
    int[ ,] x = prob.AddColumns(dim1 ,dim2)
                   .WithType(Optimizer.Objects.ColumnType.Binary)
                   .ToArray();

See VariableBuilderColumnArray2Builder for details of how to modify the specification in the builder.
