Blazor WASM异常会导致数百个额外的套接字和连接异常



我刚开始学习Blazor WASM(通常我是一名后端开发人员(，我对经常发生的事情感到困惑。

这可能是一个很难回答的问题，但请耐心等待

为什么Blazor经常无休止地抛出异常

它始于这样一个具体的例外，我仍然理解这一点(很明显，作为一个完全的Blazor新手，我不知道自己在做什么；但唯一相关的部分是抛出了一个例外(：

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
Unhandled exception rendering component: Microsoft.AspNetCore.Components.Forms.InputNumber`1[System.Int32] requires a cascading parameter of type EditContext. For example, you can use Microsoft.AspNetCore.Components.Forms.InputNumber`1[[System.Int32, System.Private.CoreLib, Version=5.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]] inside an EditForm.
System.InvalidOperationException: Microsoft.AspNetCore.Components.Forms.InputNumber`1[System.Int32] requires a cascading parameter of type EditContext.

但后来这种情况发生了，而且还在继续：

发生异常的组件非常简单。基本上，我刚刚开始对一些领域进行实验(正如我所指出的，我显然不知道自己在做什么，但这并不相关，除非它直接导致了上述异常的洪流(：

@page "/test"
<InputNumber TValue="int" ValueChanged="numberEntered"></InputNumber>
<p>The number you entered is: </p>
<InputText @ref="inputText"></InputText>
@code {
InputText inputText;
void numberEntered(int number)
{
inputText.Value = number.ToString();
}
}

为我修复此问题的是检查"；启用仅我的代码"；框。

调试->选项->概述->启用仅我的代码

您"简单的"；这段代码打破了一些规则。

我赞同@MisterMagoo的说法。从服务器开始，使调试变得容易。

  1. 输入控件需要在具有有效EditContext或Model的EditForm内部
  2. 通常应该使用@bind-Value将字段或属性绑定到控件，如下所示。阅读有关绑定的内容
  3. InputText.Value在组件上设置一个参数-nono

下面是一个有效的代码版本：

<EditForm Model="model">
<InputNumber TValue="int" @bind-Value="model.Value"></InputNumber>
</EditForm>
<div>@model.Value</div>
@code {
Model model = new Model() { Value = 4 };
class Model
{
public int Value { get; set; } = 0;
}
}

开始使用MSDocs-Blazor或其他Blazor引用。在我早期，它是我的圣经。

您的原始错误很好地表明了问题所在：

未处理的异常呈现组件：Microsoft.AspNetCore.Components.Forms.InputNumber`1[System.Int32]需要EditContext类型的级联参数。例如，您可以在EditForm中使用Microsoft.AspNetCore.Components.Forms.InputNumber`1[[System.Int32，System.Private.CoreLib，Version=5.0.0，Culture=neutral，PublicKeyToken=7cc85d7bea7798e]]。

InputNumber是一个内置的number类型输入，它需要EditContext类型的CascadingValue。请阅读此处的级联参数和值。
