我使用以下代码将XML转换为EXCEL文件。我正在使用.net windows应用程序。但输出excel文件仅显示具有4行计数的标题数据。它不是从数据集中读取所有值。数据集具有所有值。
我还有其他方法可以实现吗？
private void Convert_Click(object sender, EventArgs e)
{
progressBar1.Value = 0;
if (checkBox1.Checked && txtCustomeFileName.Text != "" && txtXmlFilePath.Text != "") // using Custome Xml File Name
{
if (File.Exists(txtXmlFilePath.Text))
{
string CustXmlFilePath = Path.Combine(new FileInfo(txtXmlFilePath.Text).DirectoryName, txtCustomeFileName.Text); // Creating Path for Xml Files
System.Data.DataTable dt = CreateDataTableFromXml(txtXmlFilePath.Text);
ExportDataTableToExcel(dt, CustXmlFilePath);
MessageBox.Show("Conversion Completed!!");
}
}
else if (!checkBox1.Checked || txtXmlFilePath.Text != "") // Using Default Xml File Name
{
if (File.Exists(txtXmlFilePath.Text))
{
FileInfo fi = new FileInfo(txtXmlFilePath.Text);
string XlFile = fi.DirectoryName + "\\" + fi.Name.Replace(fi.Extension, ".xlsx");
System.Data.DataTable dt = CreateDataTableFromXml(txtXmlFilePath.Text);
ExportDataTableToExcel(dt, XlFile);
MessageBox.Show("Conversion Completed!!");
}
}
else
{
MessageBox.Show("Please Fill Required Feilds!!");
}
}
// Creating DataTable With Xml Data
public System.Data.DataTable CreateDataTableFromXml(string XmlFile)
{
System.Data.DataTable Dt = new System.Data.DataTable();
try
{
DataSet ds = new DataSet();
ds.ReadXml(XmlFile);
Dt.Load(ds.CreateDataReader());
}
catch (Exception ex)
{
}
return Dt;
}
private void ExportDataTableToExcel(System.Data.DataTable table, string Xlfile)
{
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
Workbook book = excel.Application.Workbooks.Add(Type.Missing);
excel.Visible = false;
excel.DisplayAlerts = false;
Worksheet excelWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)book.ActiveSheet;
excelWorkSheet.Name = table.TableName;
progressBar1.Maximum = table.Columns.Count;
for (int i = 1; i < table.Columns.Count + 1; i++) // Creating Header Column In Excel
{
excelWorkSheet.Cells[1, i] = table.Columns[i - 1].ColumnName;
if (progressBar1.Value < progressBar1.Maximum)
{
progressBar1.Value++;
int percent = (int)(((double)progressBar1.Value / (double)progressBar1.Maximum) * 100);
progressBar1.CreateGraphics().DrawString(percent.ToString() + "%", new System.Drawing.Font("Arial", (float)8.25, FontStyle.Regular), Brushes.Black, new PointF(progressBar1.Width / 2 - 10, progressBar1.Height / 2 - 7));
System.Windows.Forms.Application.DoEvents();
}
}
progressBar1.Maximum = table.Rows.Count;
for (int j = 0; j < table.Rows.Count; j++) // Exporting Rows in Excel
{
for (int k = 0; k < table.Columns.Count; k++)
{
excelWorkSheet.Cells[j + 2, k + 1] = table.Rows[j].ItemArray[k].ToString();
}
if (progressBar1.Value < progressBar1.Maximum)
{
progressBar1.Value++;
int percent = (int)(((double)progressBar1.Value / (double)progressBar1.Maximum) * 100);
progressBar1.CreateGraphics().DrawString(percent.ToString() + "%", new System.Drawing.Font("Arial", (float)8.25, FontStyle.Regular), Brushes.Black, new PointF(progressBar1.Width / 2 - 10, progressBar1.Height / 2 - 7));
System.Windows.Forms.Application.DoEvents();
}
}
book.SaveAs(Xlfile);
book.Close(true);
excel.Quit();
Marshal.ReleaseComObject(book);
Marshal.ReleaseComObject(book);
Marshal.ReleaseComObject(excel);
}
}
我还可以使用其他方法吗？

下面的代码使用oledb编写一个包含xml值的新excel文件。它使用xml linq来解析xml文件。
