运行ASP Dot net core 2.0时的问题 - 使用角度4材料的MVC 6应用程序

Question

我用Angular创建了一个ASP.Net核心Web应用程序like in image。成功创建应用程序后，解决方案运行良好，输出完全来自浏览器。

之后，我将角度材料包含在上述项目中。下面是package.json

.{
  "name": "WebApplication1",
  "private": true,
  "version": "0.0.0",
  "scripts": {
    "test": "karma start ClientApp/test/karma.conf.js"
  },
  "devDependencies": {
    "@angular/animations": "5.0.2",
    "@angular/common": "5.0.2",
    "@angular/compiler": "5.0.2",
    "@angular/compiler-cli": "5.0.2",
    "@angular/core": "5.0.2",
    "@angular/forms": "5.0.2",
    "@angular/http": "5.0.2",

    "karma-webpack": "2.0.3",
    "preboot": "4.5.2",
    "raw-loader": "0.5.1",
    "reflect-metadata": "0.1.10",
    "rxjs": "5.5.5",
    "style-loader": "0.18.2",
    "to-string-loader": "1.1.5",
    "typescript": "2.4.1",
    "url-loader": "0.5.9",
    "webpack": "2.5.1",
    "webpack-hot-middleware": "2.18.2",
    "webpack-merge": "4.1.0",
    "zone.js": "0.8.18"
  },
  "dependencies": {
    "@angular/cdk": "^5.0.1"
  }
}

在使用npm安装角度材料后，我在app.server.module.ts中添加了所有角度/材质模块导入代码。如下所示：

import {  MatFormFieldModule } from '@angular/material';

并将MatFormFieldModule导入NgModule。

我的HTML就像：

<mat-form-field>
    <textarea matInput placeholder="Leave a comment"></textarea>
</mat-form-field>

最后，以下错误将在浏览器中出现：

“mat-form-field”是未知元素

请帮我简短一下这个问题。

Answer 1

将模块下方导入app.server.module.ts。

import { NgModule } from '@angular/core';
import { MatInputModule, MatFormFieldModule } from '@angular/material';


@NgModule({
  imports: [
    MatInputModule,
    MatFormFieldModule
  ],
})
export class serverModule {
}

声明你的组件例如。 Index.component.ts如下所示声明到您的模块中。

@NgModule({
  imports: [
    MatInputModule,
    MatFormFieldModule
  ],
  declarations : [
    IndexComponent.ts
  ]
})
export class serverModule {
}

然后进入你的Index.component.html写这个。

<form class="example-form">
  <mat-form-field class="example-full-width">
    <input matInput placeholder="Favorite food" value="Sushi">
  </mat-form-field>

  <mat-form-field class="example-full-width">
    <textarea matInput placeholder="Leave a comment"></textarea>
  </mat-form-field>
</form>

注意。在所有这些步骤之前，你应该将setup angular material纳入你的项目。

对于要在项目中使用的任何角度材料模块，应首先将其Mat ...模块导入到您正在使用的模块中。就像上面一样。
