事实证明这比我想象的要棘手一些.这是一个代码示例:

Turns out this is a bit thornier than I thought. Here's a code example:

var data = new int[4,3]
{
    { 1, 2, 3, },
    { 4, 5, 6, },
    { 7, 8, 9, },
    { 10, 11, 12 },
};

var rowCount = data.GetLength(0);
var rowLength = data.GetLength(1);

for (int rowIndex = 0; rowIndex < rowCount; ++rowIndex)
{
    var row = new DataGridViewRow();

    for(int columnIndex = 0; columnIndex < rowLength; ++columnIndex)
    {
        row.Cells.Add(new DataGridViewTextBoxCell()
            {
                Value = data[rowIndex, columnIndex]
            });
    }

    dataGridView1.Rows.Add(row);
}
