我在 C# 控制臺應用程序中執行我的存儲過程時遇到問題，我不知道問題是什么。你能看一下嗎？string path="";StringBuilder sb = new StringBuilder();StringBuilder sqlErrorMessages = new StringBuilder("Sql Exception:\n");try{     SqlConnection conn = new SqlConnection("Data Source=DESKTOP-M3IMRLE\\SQLEXPRESS; Initial Catalog = db2; Integrated security=true");    Console.WriteLine("Enter path : ");    path = Console.ReadLine();    conn.Open();    SqlCommand cmd = new SqlCommand();    SqlCommand command = new SqlCommand("EXECUTE main.mainproc @path='" + path + "'", conn);    if(command!=null)    {         Console.WriteLine("JSON loaded");    }      conn.Close();}catch(SqlException ex){    sqlErrorMessages.AppendFormat("Message: {0}\n", ex.Message);}
