c# - 如何从 Blazor 中的类引用属性

Question

我有一个简单的 Blazor 应用程序。

我的 .Razor 页面的 HTML 部分有一个标签。在 @code 部分中，我有一个带有一些属性的公共(public)类，我试图简单地在标签中显示我的类中的值。

代码如下:

<label>@How To Display EmailAddressHere</label>

<label>@How To Display Body</label>

@code {

    public class EmailItems
    {
    public string EmailAddress { get; set; }
    public string Body { get; set; }
    }

    protected override void OnInitialized()
    {

        var emailItems = new EmailItems()
            {
                Body = "testBody",
                EmailAddress= "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c9a3ada6ac89aea4a8a0a5e7aaa6a4" rel="noreferrer noopener nofollow">[email protected]</a>",
            };
    }
}

您需要创建一个 EmailItems 类型的字段或属性并分配它而不是变量。

<label>@emailItem.EmailAddress </label>

<label>@emailItem.Body </label>

@code {

    EmailItems emailItem;

    public class EmailItems
    {
        public string EmailAddress { get; set; }
        public string Body { get; set; }
    }

    protected override void OnInitialized()
    {

            this.emailItem = new EmailItems()
            {
                Body = "testBody",
                EmailAddress= "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="cca6a8a3a98caba1ada5a0e2afa3a1" rel="noreferrer noopener nofollow">[email protected]</a>",
            };
    }
}
