c# - 是否可以将 Excel/CSV 数据从剪贴板粘贴到 C# 中的 DataGridView？

Question

我使用 DataGridView 控件来管理一个简单的字典(几列和几百行)。 DataGridView 的功能几乎已经足够了。我可以添加新行、修改值并将数据从其中复制到 Excel。我无法做的一件事是将数据从 Excel 复制到我的控件。某些属性可以吗？或者是否需要一些代码来执行此操作？

这是从 codeprojet 文章中编辑的。略有不同 `

private void PasteClipboard()
        {
            try
            {
                string s = Clipboard.GetText();
                string[] lines = s.Split('\n');
                int iFail = 0, iRow = dgData.CurrentCell.RowIndex;
                int iCol = dgData.CurrentCell.ColumnIndex;
                DataGridViewCell oCell;
                if (dgData.Rows.Count < lines.Length)
                    dgData.Rows.Add(lines.Length-1);
                foreach (string line in lines)
                {
                    if (iRow < dgData.RowCount && line.Length > 0)
                    {
                        string[] sCells = line.Split('\t');
                        for (int i = 0; i < sCells.GetLength(0); ++i)
                        {
                            if (iCol + i < this.dgData.ColumnCount)
                            {
                                oCell = dgData[iCol + i, iRow];

                                {

                                                              oCell.ValueType);
                                      //  oCell.Style.BackColor = Color.Tomato;
                                    }
                                    else
                                        iFail++;
                                    //only traps a fail if the data has changed 
                                    //and you are pasting into a read only cell
                                }
                            }
                            else
                            { break; }
                        }
                        iRow++;
                    }
                    else
                    { break; }
                    if (iFail > 0)
                        MessageBox.Show(string.Format("{0} updates failed due" +
                                        " to read only column setting", iFail));
                }
            }
            catch (FormatException)
            {
                MessageBox.Show("The data you pasted is in the wrong format for the cell");
                return;
            }
        }
