Try this:

minValue = Common.Instance.LstSignalData[nCnt].DictSignalPlotData.Values.Min();
dataGridView_Head.Rows[nIndex].Cells["Min"].Value = Convert.ToDouble(minValue);

试试这个

Convert.ToDouble(minValue);

尝试使用Cells集合中的索引。

minValue = Common.Instance.LstSignalData[nCnt].DictSignalPlotData.Values.Min(); dataGridView_Head.Rows[nIndex].Cells[nCellIndex].Value = (double)minValue;
