如何传一个函数给用户控件?

Question

我想传一个函数给一个用户控件，这个函数在用户控件中多次用到，但我用下面的代码得到了错误，请问如果做?谢谢！

Error 1 Inconsistent accessibility: property type 'UserControl_RunCode.delegateGetDynamicDimFromControl' is less accessible than property 'UserControl_RunCode.GetDynamicDimFromControl'
E:\ASP.NET4.0_Calculator\hicalc\UserControl\RunCode.ascx.cs 22 45 E:\ASP.NET4.0_Calculator\hicalc\

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class UserControl_RunCode : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }

    public int InputedID //It's OK
    {
        get { return Convert.ToInt32(ViewState["InputedID"].ToString()); }
        set { ViewState["InputedID"] = value.ToString(); }
    }

    delegate dynamic[] delegateGetDynamicDimFromControl(Panel PanelInput);

    public delegateGetDynamicDimFromControl GetDynamicDimFromControl //It's wrong
    {
        get {
              return (delegateGetDynamicDimFromControl)ViewState["GetDynamicDimFromControl"];
            }
        set {
             ViewState["GetDynamicDimFromControl"] = value;
            }
    }

}

因為您在 public 的member 中使用了 僅具有 internal 存取權的 method.....

試著把 delegateGetDynamicDimFromControl 的存取修飾詞改為 public 看看~
