如果你新建一个项目的话，首先要添加Microsoft.Office.Core 与Microsoft.Office.Interop.Exce这两个应用，然后就能很方便的操作了，示例代码（只实现了简单的读写）：
1
PRivateExcel._applicationexcelApp;
2
privateWorkbook wbclass;
3
4
excelApp = newExcel.Application();
5
6
objectobjOpt = System.Reflection.Missing.Value;
7
8
wbclass = (Workbook)excelApp.Workbooks.Open("E:\Book6.xlsx", objOpt, false, objOpt, objOpt, objOpt, true, objOpt, objOpt, true, objOpt, objOpt, objOpt, objOpt, objOpt);
上面声明，引用，并把要操作的 excel 的路径传给他
得到所有的表名：
1
List<string> list = new List<string>();
2
Excel.Sheets sheets = wbclass.Worksheets;
3
string sheetNams = string.Empty;
4
foreach (Excel.Worksheet sheet in sheets)
5
{
6
list.Add(sheet.Name);
7
}
获取某个表中的数据，这里获取的是sheet 表中的：
01
publicExcel.Worksheet GetWorksheetByName(string name)
02
{
03
Excel.Worksheet sheet = null;
04
Excel.Sheets sheets = wbclass.Worksheets;
05
foreach (Excel.Worksheet s in sheets)
06
{
07
if(s.Name == name)
08
{
09
sheet = s;
10
break;
11
}
12
}
13
returnsheet;
14
}
15
16
publicSystem.Data.DataTable GetDateTable(string name)
17
{
18
System.Data.DataTable dt = newSystem.Data.DataTable();
19
20
var worksheet = GetWorksheetByName(name); //调用上面的方法，利用表名得到这张表
21
22
string cellContent;
23
24
intiRowCount = worksheet.UsedRange.Rows.Count;
25
intiColCount = worksheet.UsedRange.Columns.Count;
26
Excel.Range range;
27
for (intiRow = 1; iRow <= iRowCount; iRow++)
28
{
29
DataRow dr = dt.NewRow();
30
31
for (intiCol = 1; iCol <= iColCount; iCol++)
32
{
33
range = (Excel.Range)worksheet.Cells[iRow, iCol];
34
35
cellContent = (range.Value2 == null) ? "": range.Text.ToString();
36
37
if(iRow == 1)
38
{
39
dt.Columns.Add(cellContent);
40
}
41
else
42
{
43
dr[iCol - 1] = cellContent;
44
}
45
}
46
47
if(iRow != 1)
48
dt.Rows.Add(dr);
49
}
50
51
returndt;
52
53
}
上面得到的只是
1
System.Data.DataTable
如何把数据取出来，请看下面：
1
var dataTable = GetDateTable("Sheet1"); //调用上面的方法
2
3
foreach (DataRow row indataTable.Rows)
4
{
5
stringa = (string)row[2];
6
stringb = (string)row[4];
7
8
}
