C＃Console ExcelからSQLへのインポート

Question

私はthisの参照でC＃を使用してSQLにExcelデータをインポートしています。しかし、私はこれをコンソールプログラムにしたい。

どうすれば助けてください。

ありがとうございます。

コード：

protected void Upload(object sender, EventArgs e) 

{// アップロードし、ファイルを保存し 文字列excelPath = Server.MapPathの（ "〜/ファイル/"）+ Path.GetFileName（FileUpload1.PostedFile.FileName）。 FileUpload1.SaveAs（excelPath）;

string conString = string.Empty; 
string extension = Path.GetExtension(FileUpload1.PostedFile.FileName); 
switch (extension) 
{ 
    case ".xls": //Excel 97-03 
     conString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString; 
     break; 
    case ".xlsx": //Excel 07 or higher 
     conString = ConfigurationManager.ConnectionStrings["Excel07+ConString"].ConnectionString; 
     break; 

} 
conString = string.Format(conString, excelPath); 
using (OleDbConnection excel_con = new OleDbConnection(conString)) 
{ 
    excel_con.Open(); 
    string sheet1 = excel_con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null).Rows[0]["TABLE_NAME"].ToString(); 
    DataTable dtExcelData = new DataTable(); 

    //[OPTIONAL]: It is recommended as otherwise the data will be considered as String by default. 
    dtExcelData.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)), 
      new DataColumn("Name", typeof(string)), 
      new DataColumn("Salary",typeof(decimal)) }); 

    using (OleDbDataAdapter oda = new OleDbDataAdapter("SELECT * FROM [" + sheet1 + "]", excel_con)) 
    { 
     oda.Fill(dtExcelData); 
    } 
    excel_con.Close(); 

    string consString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString; 
    using (SqlConnection con = new SqlConnection(consString)) 
    { 
     using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(con)) 
     { 
      //Set the database table name 
      sqlBulkCopy.DestinationTableName = "dbo.tblPersons"; 

      //[OPTIONAL]: Map the Excel columns with that of the database table 
      sqlBulkCopy.ColumnMappings.Add("Id", "PersonId"); 
      sqlBulkCopy.ColumnMappings.Add("Name", "Name"); 
      sqlBulkCopy.ColumnMappings.Add("Salary", "Salary"); 
      con.Open(); 
      sqlBulkCopy.WriteToServer(dtExcelData); 
      con.Close(); 
     } 
    } 
} 

}

方法

protected void Upload(object sender, EventArgs e) 

は、GUIの場合に使用されます。 コンソールの場合、名前をたとえばに変更します。

static void LoadExcelMain() 
    { 
     your code here 
    } 

でメソッドを呼び出します。ここで

さ：編集あなたが

//modify : 
string extension = Path.GetExtension(FileUpload1.PostedFile.FileName); 
//to be 
string extension = Path.GetExtension(excelPath);  

//You need to add entry in App.Config for the connectionString 

//You can't to use = Server.MapPath in console application 
//Review carefully the mapping of columns in the table in the csv file 

、ファイルの拡張子を取得するには、Webアプリケーションで使用される方法を変更する必要が

static void Main(string[] args) 
{ 
    LoadExcelMain(); 
}
