Double不会以DataGridView格式输出

Question

我有一个DataGridView，我想用双精度值填充它。当值是字符串时，DataGridView填充得很好，但现在它在第一列中输出System.Double[]，在任何其他列中都不输出任何内容。我知道转换是有效的，因为我可以将双精度值打印到控制台。如何以编程方式设置所有列的格式？(我不想使用设计器)

我的代码：

Dim cols() as String = {"col1", "col2", "col3"} ' this goes on for 33 cols
Dim currentRow As String()
Dim row() As Double
Dim c As Integer

DataGridView1.Rows.Clear()
DataGridView1.ReadOnly = True
DataGridView1.DefaultCellStyle.Format = "G"
DataGridView1.ColumnCount = 33

For c = 0 To (cols.Length - 1)
     DataGridView1.Columns(c).Name = cols(c)
Next
While Not at EndOfFile ' This line and the next are semi-pseudocode, but it's the same idea
    read/parse line into currentRow
    Dim x As Integer
    For x = 0 To (currentRow.Length - 1)
        ReDim Preserve row(x)
        Double.TryParse(currentRow(x), row(x))
    Next

    With Me.DataGridView1.Rows
        .Add(row)
    End With
