異步功能

Question

我有以下結構：

這是我的控制器：

Public Function InsertRegistration() as string 

      dim res = t.Insertregistration(jsonparam.status) 

      return res 
    End Function 

這是我的課：

Public Function InsertRegistration(byval status as string) as string 

     sql.Insertregistration(status) 

     return "1" 

    End Function 

這是我的模型功能：

Public Function InsertRegistration(ByVal status As String) As Boolean 
    Dim TConnSQL As New SqlConnection(sql) 
    Dim CommSQL As New SqlClient.SqlCommand("JK_SP_INSERT_PROFILE", TConnSQL) 
    Dim paramSQL As SqlClient.SqlParameter 
    Dim data_ada As SqlDataAdapter 
    Dim dt As DataSet 
    Try 

     CommSQL.CommandType = CommandType.StoredProcedure 

     paramSQL = New SqlClient.SqlParameter("@STATUS", SqlDbType.NVarChar, 100) 
     paramSQL.Direction = ParameterDirection.Input 
     paramSQL.Value = STATUS 
     CommSQL.Parameters.Add(paramSQL) 

     CommSQL.ExecuteNonQuery() 

     InsertRegistration= True 

    Catch ex As System.Data.SqlClient.SqlException 
     WriteToText("Nbl.InsertRegistration", ex.ToString) 
     InsertRegistration= False 
    Catch ex As Exception 
     WriteToText("Nbl.InsertRegistration", ex.ToString) 
     InsertRegistration= False 
    Finally 
     If (IsNothing(CommSQL) = False) Then CommSQL.Dispose() 
     If TConnSQL.State <> ConnectionState.Closed Then TConnSQL.Close() 
    End Try 
End Function 

有沒有辦法r以異步的方式改變結果1，函數sql.Insertregistration(status)在將結果返回給客戶端後繼續在後臺運行？

Answer 1

簡單地說你的函數sql.Insertregistration(status)如下代碼：

(new Task<bool>(() => 
{ 
    return sql.Insertregistration(status); 
})).Start(); 

注：請把橫線ooperations的照顧。
