bh002- Blazor hybrid / Maui 保存设置快速教程

1. 建立工程 bh002_ORM

源码

2. 添加 nuget 包

3. 添加命名空间引用

_Imports.razor

@using BootstrapBlazor.Components

4. 添加服务

MauiProgram.cs

在 return builder.Build(); 之前加入这句

builder.Services.AddScoped();

5. 添加代码后置文件 Pages/Index.razor.cs

Index.razor.cs

using BootstrapBlazor.WebAPI.Services;
using Microsoft.AspNetCore.Components;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel;
using System.Diagnostics.CodeAnalysis;

namespace bh002_ORM.Pages;

public partial class Index
{
    [Inject, NotNull] protected IStorage Storage { get; set; }

    [DisplayName("用户名")]
    [Required(ErrorMessage = "请输入用户名")]
    public string Username { get; set; }

    IFreeSql Fsql { get; set; }

    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender)
        {
            Username = await Storage.GetValue("username","");
            if (!string.IsNullOrEmpty(Username))
            {
                StateHasChanged();
            }
        }
    }

    async Task Login()
    {
        await Storage.SetValue("username", Username);
    } 
}

6. 添加 UI

Index.razor

@page "/"
Hello, @Username
用户名:

登录

7. 执行效果

8. 添加清除按钮

Index.razor

清除

Index.razor.cs

    async Task Reset()
    {
        await Storage.RemoveValue("username");
        Username = "";
    }
