通过For-Loop添加表行

Question

I am trying to write a program that requires me to add data to a datagrid. There's a pattern, but I can't seem to figure out how to decently get this data done through a For-Loop.

This is my code without using a For-Loop:

table.Rows.Add("0", "0", "0", "0", "0");
table.Rows.Add("0", "0", "0", "1", "0");
table.Rows.Add("0", "0", "1", "0", "0");
table.Rows.Add("0", "1", "0", "0", "0");

table.Rows.Add("1", "0", "0", "0", "0");
table.Rows.Add("1", "0", "0", "1", "0");
table.Rows.Add("1", "0", "1", "0", "0");

table.Rows.Add("1", "1", "0", "0", "0");
table.Rows.Add("1", "1", "0", "1", "0");

table.Rows.Add("1", "1", "1", "0", "0");
table.Rows.Add("1", "1", "1", "1", "0");

The last zero will be dynamically generated, no need to do anything with that.

Is this somehow possible to do through a For-Loop?

Answer 1

You could use this loop, although it is not very readable. So if you can use your static code, use it.

bool allFieldsOne = false;
table.Rows.Add("0", "0", "0", "0", "0");
while (!allFieldsOne)
{
    DataRow lastRow = table.Rows[table.Rows.Count - 1];
    DataRow currentRow = table.Rows.Add();
    currentRow[4] = "0";
    for (int f = 3; f >= 0; f--)
    {
        if (lastRow.Field<string>(f) == "0")
        {
            currentRow[f] = "1";
            while (--f >= 0)
                currentRow[f] = "0";
            break;
        }
        else
        {
            currentRow[f] = "1";
            allFieldsOne = f == 0;
        }
    }
}

Would that kind of for loop pattern be useful ? (it's the pattern used for truth table which is simply binary counting)

for (int i = 0; i < 16; i++)
            {
                Console.WriteLine(
                   string.Format("{0:0000}",
                   Convert.ToInt16(Convert.ToString(i, 2)))
                );
            }
