發布到服務器后無法顯示/打開Excel文檔！ 在本地計算機上很好，但在服務器上沒有

Question

我想通過LinkBut​​ton單擊顯示excel文檔模板。 但是，在服務器端，我無法做到這一點（相反，似乎只是刷新該頁面）。

我該怎么做呢？

 public class CreateExcelDoc
    {
        public static Excel.Application app = null;
        public static Excel.Workbook workbook = null;
        public static Excel.Worksheet worksheet = null;
        public static Excel.Range workSheet_range = null;

        public CreateExcelDoc()
        {
            createDoc();
        }

        public void createDoc()
        {
            try
            {
                app = new Excel.Application();
                app.Visible = true;
                workbook = app.Workbooks.Add(1);
                worksheet = (Excel.Worksheet)workbook.Sheets[1];

            }
            catch (Exception)
            {
                //MessageBox.Show("Error!");
            }
            finally
            {
            }
        }

        public void createHeaders(int row, int col, string htext, string cell1, string cell2, int mergeColumns, string b, bool font, int size, string fcolor)

            }
        }

Answer 1

您需要在部署計算機上安裝Office interOp 運行時 ，但是我認為這不是一個好的解決方案。 看一下如何在ASP.NET中動態創建Excel文件以及如何 從C＃讀取Excel文件 。

Answer 2

Office Interop程序集從未打算用於服務器端開發。 您可能需要考慮使用Open XML。 下面的知識庫文章提供了詳細的解釋： Office的服務器端自動化的注意事項

如@AVD所述，您確實需要在服務器上安裝Office Primary Interop程序集。 另外，根據您嘗試使用的MS Office版本，64位Office Interop程序集可能不可用。
