excel文檔中嵌入對象(excel、word等)

//測試環境office2016、office365

string InsertPath= @"E:\\新建文件夾\\2.xls";//插入的文檔路徑

string openfile = string.Empty;
excelFileName = @"E:\\1.xls";//使用的文檔路徑

Application app = new Application();//創建一個資源對象
//app.Visible = true;
Workbook wb = app.Workbooks.Open(Filename: openfile );//打excel文檔
Worksheet sht = wb.Worksheets[1];//選擇第一個活動工作目錄

OLEObjects objs = sht.OLEObjects();//創建一個OLEObjects對象
for (int i = objs.Count; i >= 1; i--)
objs.Item(i).Delete();

Range rng = null;
rng = sht.Cells[1, 5];//插入的位置 第1:行 第5：列
rng.Select();

//將文檔插入
OLEObject obj = objs.Add(Filename: InsertPath
, Link: false
, DisplayAsIcon: true
, IconFileName: "excel.exe"
, IconIndex: 0
, IconLabel: "aaa"
, Left: rng.Left
, Top: rng.Top
);
obj.Select();
rng.Select();
wb.Save();
wb.Close();
