来自选项卡式 Excel 电子表格 C# .NET 的嵌套 XML
我正在尝试将 excel 电子表格中多张工作表中的数据格式化为嵌套 xml
我想结束的xml是
<root>
<Tab>
<TabName>Tab 0</TabName>
<Products>
<ItemId>11111</ItemId>
<Image>/images/100.jpg</Image>
<Link>http://www.google.com</Link>
</Products>
<Products>
<ItemId>22222</ItemId>
<Image>/images/100.jpg</Image>
<Link>http://www.google.com</Link>
</Products>
</Tab>
<Tab>
<TabName>Tab 1</TabName>
<Products>
<ItemId>11111</ItemId>
<Image>/images/100.jpg</Image>
<Link>http://www.google.com</Link>
</Products>
<Products>
<ItemId>22222</ItemId>
<Image>/images/100.jpg</Image>
<Link>http://www.google.com</Link>
</Products>
</Tab>
</root>
我正在使用的代码是
public static string Ajax_ReadExcel()
{
OleDbConnection objConn = null;
System.Data.DataTable dt = null;
string fileName = HttpRuntime.AppDomainAppPath + "ExcelUpload\\ProductData.xlsx";
DataSet objDataset1 = new DataSet("root");
try
{
// Connection String. Change the excel file to the file you
// will search.
String connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + fileName + ";Extended Properties=Excel 8.0;";
connString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0}; Extended Properties=Excel 12.0;", fileName);
// Create connection object by using the preceding connection string.
objConn = new OleDbConnection(connString);
// Open connection with the database.
objConn.Open();
// Get the data table containg the schema guid.
dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
//dt = objConn.E
if (dt == null)
{
return null;
}
String[] excelSheets = new String[dt.Rows.Count];
int i = 0;
// Add the sheet name to the string array.
foreach (DataRow row in dt.Rows)
{
excelSheets[i] = row["TABLE_NAME"].ToString();
i++;
}
// Loop through all of the sheets if you want too...
for (int j = 0; j < excelSheets.Length; j++)
{
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM ["+excelSheets[j]+"]", objConn);
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
objAdapter1.SelectCommand = objCmdSelect;
objAdapter1.Fill(objDataset1, "Products");
// Query each excel sheet.
//Trace.Write(objDataset1.GetXml());
}
//ltrContent.Text += "<hr/>" + excelSheets;
objConn.Close();
//return excelSheets;
}
catch (Exception ex)
{
return null;
}
finally
{
// Clean up.
if (objConn != null)
{
objConn.Close();
objConn.Dispose();
}
if (dt != null)
{
dt.Dispose();
}
}
return objDataset1.GetXml();
}
我可以将所有的 excel 数据加载到一个 xml 集中
<root>
<Products>...</Products>
</root>
,但我对 C# DataSet 不够熟悉,无法将输出转换为我需要的嵌套 xml。
