异步功能

Question

我有以下结构：

这是我的控制器：

Public Function InsertRegistration() as string 

      dim res = t.Insertregistration(jsonparam.status) 

      return res 
    End Function 

这是我的课：

Public Function InsertRegistration(byval status as string) as string 

     sql.Insertregistration(status) 

     return "1" 

    End Function 

这是我的模型功能：

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 

有没有办法r以异步的方式改变结果1，函数sql.Insertregistration(status)在将结果返回给客户端后继续在后台运行？

简单地说你的函数sql.Insertregistration(status)如下代码：

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

注：请把横线ooperations的照顾。
