Asp.net core 如何将模型传输到Blazor服务器端的Razor组件？

我正在使用Blazor服务器端创建聊天室

由于接收消息和发送消息的方式不同，我制作了一个名为

MsgModel

using Microsoft.AspNetCore.Components;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace BlazorApp1
{
    public class MsgModel: ComponentBase
    {
        public string MsgText { get; set; }
    }
}

razor组件

ReceiveMsg.razor

和

SendMsg.razor

基于此模型

@inherits MsgModel
<h3>ReceiveMsg</h3>@MsgText    

现在的问题是：在

for

块中，我应该将

\u MsgModel

传输到组件。同时，我还不知道如何转移它

你能帮帮我吗？谢谢。

最后，我找到了一个奇怪而愚蠢的方法来解决这个问题

我将这些代码添加到

MsgModel

：

[Parameter]
        public MsgModel TransferModel
        {
            set
            {
                CopyAll(value, this);
            }
        }
        private void CopyAll<T>(T source, T target)
        {
            var type = typeof(T);
            foreach (var sourceProperty in type.GetProperties())
            {
                if (sourceProperty.Name != "TransferModel")
                {
                    var targetProperty = type.GetProperty(sourceProperty.Name);
                    targetProperty.SetValue(target, sourceProperty.GetValue(source, null), null);
                }
            }
        }

这是多么愚蠢的方式啊

@page "/"

@foreach (MsgModel _MsgModel in MsgList)
{
    if (_MsgModel.GetType() == typeof(ReceiveMsg))
    {
        <ReceiveMsg></ReceiveMsg>
    }
    else
    {
        <SendMsg></SendMsg>
    }
}
<div id="inputDiv">
    <EditForm Model="_InputMsgModel" OnValidSubmit="@SubmitText">
        <InputText @bind-Value="_InputMsgModel.MsgText" />
    </EditForm>
</div>

@code{
    protected MsgModel _InputMsgModel { get; set; } = new MsgModel();
    protected List<MsgModel> MsgList { get; set; } = new List<MsgModel>();
     protected void SubmitText()
    {
        SendMsg _SendMsg = new SendMsg();
        _SendMsg.MsgText = _InputMsgModel.MsgText;
        MsgList.Add(_SendMsg);
    }
}

[Parameter]
        public MsgModel TransferModel
        {
            set
            {
                CopyAll(value, this);
            }
        }
        private void CopyAll<T>(T source, T target)
        {
            var type = typeof(T);
            foreach (var sourceProperty in type.GetProperties())
            {
                if (sourceProperty.Name != "TransferModel")
                {
                    var targetProperty = type.GetProperty(sourceProperty.Name);
                    targetProperty.SetValue(target, sourceProperty.GetValue(source, null), null);
                }
            }
        }

@foreach (Models.MsgModel _MsgModel in MsgList)
    {
        if (_MsgModel.GetType() == typeof(ReceiveMsg))
        {
            <ReceiveMsg ShowFullImage="@ShowFullImage" TransferModel="_MsgModel"></ReceiveMsg>
        }
        else
        {
            <SendMsg ShowFullImage="@ShowFullImage" TransferModel="_MsgModel"></SendMsg>
        }
    }
