我正在使用以下代碼將Excel數據從剪貼板讀取到C#數據表格中。代碼相對不變,從this answer到this question。然後將數據表作爲數據源添加到DataGridView控件中進行操作。將數據從剪貼板讀入DataTable時保留空的Excel單元格
但是,在我的Excel數據中,我有空白/空單元格,我需要保留,這段代碼沒有做(空白單元格跳過,有效地壓縮每一行,沒有空的空間;缺少空單元格來自Excel XML)。傳輸到數據表時,如何保留空單元格?
方法:
private DataTable ParseClipboardData(bool blnFirstRowHasHeader)
{
var clipboard = Clipboard.GetDataObject();
if (!clipboard.GetDataPresent("XML Spreadsheet")) return null;
StreamReader streamReader = new StreamReader((MemoryStream)clipboard.GetData("XML Spreadsheet"));
streamReader.BaseStream.SetLength(streamReader.BaseStream.Length - 1);
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml(streamReader.ReadToEnd());
XNamespace ssNs = "urn:schemas-microsoft-com:office:spreadsheet";
DataTable dt = new DataTable();
var linqRows = xmlDocument.fwToXDocument().Descendants(ssNs + "Row").ToList<XElement>();
for (int x = 0; x < linqRows.Max(a => a.Descendants(ssNs + "Cell").Count()); x++)
dt.Columns.Add("Column " + x.ToString());
int intCol = 0;
DataRow currentRow;
linqRows.ForEach(rowElement =>
{
intCol = 0;
currentRow = dt.Rows.Add();
rowElement.Descendants(ssNs + "Cell")
.ToList<XElement>()
.ForEach(cell => currentRow[intCol++] = cell.Value);
});
if (blnFirstRowHasHeader)
{
int x = 0;
foreach (DataColumn dcCurrent in dt.Columns)
dcCurrent.ColumnName = dt.Rows[0][x++].ToString();
dt.Rows.RemoveAt(0);
}
return dt;
}
擴展方法:
public static XDocument fwToXDocument(this XmlDocument xmlDocument)
{
using (XmlNodeReader xmlNodeReader = new XmlNodeReader(xmlDocument))
{
xmlNodeReader.MoveToContent();
var doc = XDocument.Load(xmlNodeReader);
return doc;
}
}
人爲的例子來說明:(Excel的2015)在Excel
範圍,複製到剪貼板
的DataGridView在WinForm的,以數據表作爲數據源
謝謝,這個伎倆! – natedogg
