在Blazor中发送复杂对象通常涉及到序列化对象以便在客户端和服务器之间传输。以下是将复杂对象发送到Blazor页面的基本步骤和相关概念:
public class ComplexObject
{
public int Id { get; set; }
public string Name { get; set; }
public List<string> Items { get; set; }
}
[ApiController]
[Route("[controller]")]
public class DataController : ControllerBase
{
[HttpGet("complex")]
public IActionResult GetComplexObject()
{
var complexObject = new ComplexObject
{
Id = 1,
Name = "Sample Object",
Items = new List<string> { "Item1", "Item2", "Item3" }
};
return Ok(complexObject);
}
}
@page "/fetchdata"
@inject HttpClient Http
<h3>Complex Object Data</h3>
<p>Id: @complexObject.Id</p>
<p>Name: @complexObject.Name</p>
<ul>
@foreach (var item in complexObject.Items)
{
<li>@item</li>
}
</ul>
@code {
private ComplexObject complexObject;
protected override async Task OnInitializedAsync()
{
complexObject = await Http.GetFromJsonAsync<ComplexObject>("api/data/complex");
}
}
[JsonProperty]
或[DataMember]
等特性来指定序列化行为。@bind
或@bind:event
指令。通过以上步骤,你可以将复杂对象从后端发送到Blazor页面,并在前端显示这些数据。
