Question

我有以下结构：

这是我的控制者：

   Public Function InsertRegistration() as string

          dim res = t.Insertregistration(jsonparam.status)

          return res
   End Function

这是我的班级：

   Public Function InsertRegistration(byval status as string) as string

         sql.Insertregistration(status)

         return "1"

   End Function

这是我的模特功能：

    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

有一种方法可以在我将结果返回给客户端后以异步方式返回结果1，使函数sql.Insertregistration(status)在后台继续运行吗？

只需将您的函数sql.Insertregistration(status)设置为以下代码：

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

注意：请注意跨线程操作。
