引数の例外は、私が言う私のプログラムを実行しようとすると、私はエラーを取得していますSQL接続

Question

で未処理だった - using (conn = new SqlConnection(connstring))

で

An unhandled exception of type 'System.ArgumentException' occurred in System.Data.dll 

Additional information: Initialiseringsstrengens format does not match the specification starting at index 0. 

そのため、全体のコード -

public partial class MainWindow : Window 
{ 


    public SqlConnection conn; 
    public SqlCommand cmd; 
    string connstring = (@"Data Source=SINDALSQL\MSSQL14; Initial Catalog=OminiData; Integrated Security =True"); 
    string sql = ("SELECT Mærke, Model, Årgang, [Motor Type], Krydsmål, Centerhul, Møtrik, Bolter, Dæk, Fælge FROM Hjuldata"); 

    private void binddata() 
    { 
     DataSet1 ds = new DataSet1(); 
     using (conn = new SqlConnection(connstring)) 
     { 
      cmd = new SqlCommand(sql, conn); 
      SqlDataAdapter adp = new SqlDataAdapter(); 
      conn.Open(); 
      adp.SelectCommand = cmd; 
      adp.Fill(ds, "Hjuldata"); 
      hjuldata.DataContext = ds; 
     } 
    }`
