Question

I need to create container like this: Container.Add(RowIndex, ValueIndex);

I know Dictionary just have Key and Value and this is not good for me.
And i havent no idea how to use 2 containers to create Row, Index how i want.

So example:

Container[Row][Index]:
Container[0][0] = "Apple";
Container[0][1] = "Orange";
Container[1][0] = "Number";

Because im trying use this container for read sql. When i got next result it add to current row value +1. And Index mean field value.

In code:

                int row = 0;

                while (ObjReader.Read())
                {
                    foreach (var result in ObjReader)
                        ReadList.Add(row, result.ToString());

                    row++;
                }

                ObjReader.NextResult();

this is for reading

and now get result to another Class

    public string Field(int row, int index)
    {
        return ReadList[row][index];
    }

It seems you’re looking for a List of Lists.

List<List<string>> results = new List<List<string>>();

while (haveMoreRows)
{
    List<string> nextRow = new List<string>();
    foreach (var item in currentRow)
        nextRow.Add(item.ToString());

    results.Add(nextRow);
}

Now you can do something like: results[2][1] to get the value at the 3rd row in the 2nd column.
