ASP.NET Core Blazor: 两种IJSRuntime依赖注入的方式

• 1）将 IJSRuntime 抽象注入Razor组件或者页面(.razor ) 中：

  ...
  public partial class ToolsWidget
  {
      [Inject]
      private IJSRuntime JSRuntime { set; get; }
      
      ....

• 2）将 IJSRuntime 抽象注入一个类 (.cs )中：

• ...    
  public class CameraUI : ICameraUI
  {
      private readonly IJSRuntime _jsRuntime;
  
      public CameraUI(IJSRuntime jsRuntime)
      {
          _jsRuntime = jsRuntime;
      }
      ....

  此时，2）就可以像 1）一样注入到普通页码或者组件中了。

•     ...
  public partial class ToolsWidget
  {
      ...
  
      [Inject]
      private ICameraUI CameraUI { set; get; }
  
      ...
