问题描述
我要读取第一张纸的唯一标题（不是数据），形成一张包含多张纸的excel文档。我不想在内存中加载完整的文档，因此没有DOM方法。我正在使用的代码读取文件的第二张而不是第一张？
I've to read the only headers (not data)of the first sheet form an excel document with multiple sheets . I don't want to load the complete document in the memory hence no DOM approach. The code I'm using reads the second sheet of the file and not the first ?
internal DataTable GetSchema(string fileName)
{
int i = 0;
DataTable dataTable = new DataTable();
using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(fileName, false))
{
WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
foreach (WorksheetPart worksheetPart in workbookPart.WorksheetParts)
{
OpenXmlReader reader = OpenXmlReader.Create(worksheetPart);// (
while (reader.Read())
{
if (reader.ElementType == typeof(Row))///loops through row
{
reader.ReadFirstChild();
if (i > 1)
{
return dataTable;
// we have recieved all column names till here
}
i++; //increments for the first time which means we are reading columns
do
{
if (reader.ElementType == typeof(Cell))
{
Cell c = (Cell)reader.LoadCurrentElement();
string cellValue = string.Empty;
if (c.CellValue != null)
{
if (c.DataType != null && c.DataType == CellValues.SharedString)
{
SharedStringItem ssi = workbookPart.SharedStringTablePart.SharedStringTable.Elements<sharedstringitem>().ElementAt(int.Parse(c.CellValue.InnerText));
cellValue = Convert.ToString(ssi.InnerText);
}
else
{
cellValue = Convert.ToString(c.CellValue.InnerText);
}
}
else
{
cellValue = c.InnerText;
}
if (i <= 1)
{
dataTable.Columns.Add(cellValue);
}
else
{
break;
}
}
} while (reader.ReadNextSibling());
}
}
}
return dataTable;
}
}
excel文件有三张：
1.记录< br $>
2.sa
3.da（无专栏）
和我的代码读取2（sa）的标题。
有人可以帮助我从1读取标题（记录）文件？
the excel file has three sheets :
1. records
2.sa
3.da (no columns)
and my code reads headers for the 2 (sa).
Can some one please help me to read the header from 1 (records) file ?
推荐答案
我删除了每个，尝试下面的行，它工作。
显然它看起来是纸张的顺序是当我们直接阅读它时反转。
WorksheetPart worksheetPart = workbookPart.WorksheetParts.Last（）;
I removed the for each, tried below line and it worked.
Apparently it looks that the order of the sheets is reversed when we read it directly.
WorksheetPart worksheetPart = workbookPart.WorksheetParts.Last();
