Handling array argument!

[C NewBe]

I am converting vb6 code to C# and I have a question regarding array argument. In vb6 the array argument below sometimes take the form of 1Dimension or MultiD where it is Redim depending on how it comes. C# does not allow this.....my question is, how do I handle it? public double[] ConvertMatrixToBase0(double[] MyMat) { long i, j; double[] ConvMat; if(MultiDimensional(MyMat) == false) //1-dimensional array { ConvMat = new double[MyMat.GetLength(1) - 1]; //ReDim ConvMat(UBound(MyMat, 1) - 1) for(i=1; i<=MyMat.GetLength(1); i++) //For i = 1 To UBound(MyMat, 1) ConvMat[i - 1] = MyMat[i]; } else //multi-dimensional array { ConvMat = new double[MyMat.GetLength(1)-1, MyMat.GetLength(2)-1]; //ReDim ConvMat(UBound(MyMat, 1) - 1, UBound(MyMat, 2) - 1) for(i=1; i<=MyMat.GetLength(1); i++) //For i = 1 To UBound(MyMat, 1) { for(j=1; j<=MyMat.GetLength(2); j++) //For j = 1 To UBound(MyMat, 2) ConvMat[i-1,j-1] = MyMat[i,j]; } } return ConvMat; }

double[,] matrix = new double[10, 10];

led mike, I don't think I did a good job describing the problem. It should have been how to handle a dynamic array argument in c#. From readings that I have done, I do not think it's possible. I think I have to use Arraylist.

You would be better off using a generic collection rather than an arraylist

I am going to look into collection but can you educate a bit about the differences between the two? Thanks

Given your example using an ArrayList you would incur a boxing/unboxing penalty everytime to stored or accessed the values since ArrayList uses object. Using a generic collection, say List you would not have this issue, with the additional benefit of being typesafe.
