準備一下，近段時間，需要把Excel的數據導入數據庫中。

引用命名空間：

using System.Configuration;
using System.Data;
using System.Data.OleDb;
using System.Data.SqlClient;

你可以寫一個方法，是去讀取Excel文檔的方法，返回DataSet數據集：

private DataSet ImportExcelToDataSet(string virtualPath, string sqlQueryStatement)
    {
        string
 
 excelConnectionString = DB.ExcelConnectionString(Server.MapPath(virtualPath));
        OleDbConnection dc = new OleDbConnection(excelConnectionString);
        OleDbDataAdapter da = new OleDbDataAdapter(sqlQueryStatement, dc);
        DataSet ds = new DataSet();
        da.Fill(ds);
        return
 
 ds;
    }

導入數據庫，在數據庫中，需要創建一個表來存儲Excel導入來的數據：

接下來，你可以使作SqlBulkCopy的方法進行復制數據庫：

try
        {
            string cs = ConfigurationManager.ConnectionStrings["InsusSqlConnectionString"].ConnectionString;
            using (SqlConnection sqlConn = new SqlConnection(cs))
            {
                
 
string sqlQueryStatement = "SELECT [Material],[Plnt],[Level],[Item],[Component],[Object description] FROM [Sheet1$]";
                string virtualPath = "~/App_Data/Book1.xlsx";

                DataSet ds = ImportExcelToDataSet(virtualPath, sqlQueryStatement);

                DataTable dt = ds.Tables[0];

                sqlConn.Open();
                using (SqlBulkCopy sqlbc = new SqlBulkCopy(sqlConn))
                {
                    sqlbc.DestinationTableName = "BOM";
                    sqlbc.ColumnMappings.Add("Material", "Material");
                    sqlbc.ColumnMappings.Add("Plnt", "Plnt");
                    sqlbc.ColumnMappings.Add("Level", "Level");
                    sqlbc.ColumnMappings.Add("Item", "Item");
                    sqlbc.ColumnMappings.Add("Component", "Component");
                    sqlbc.ColumnMappings.Add("Object description", "Object description");
                    sqlbc.WriteToServer(dt);
                    Response.Write("數據導入成功！");
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
