Blazor Web Assembly懒加载.resources.dll的实现方法
在Blazor Web Assembly应用程序中,如果您的应用程序包含多种语言的资源文件,您可能会遇到加载时间过长的问题。为了解决这个问题,可以使用Blazor Web Assembly的懒加载功能,仅在需要时动态加载资源文件。
下面是如何实现懒加载.resources.dll的代码示例:
首先,您需要在App.razor文件中添加以下代码:
Sorry, there's nothing at this address.
@code {
private LazyAssemblyLoader LazyAssemblyLoader { get; set; }
protected override void OnInitialized()
{
LazyAssemblyLoader = new LazyAssemblyLoader("MyApp.Client.resources", typeof(Program).Assembly);
}
}
在这里,您需要创建一个LazyAssemblyLoader对象,该对象将使用资源文件的命名空间名称(MyApp.Client.resources)和应用程序所在的程序集对象(typeof(Program).Assembly)来指定要加载的资源文件。
接下来,在LazyAssemblyLoader类中,您需要添加以下代码:
public class LazyAssemblyLoader : IDisposable
{
private readonly Assembly _assembly;
private readonly string _resourcesName;
private readonly Lazy _resources;
public LazyAssemblyLoader(string resourcesName, Assembly assembly)
{
_resourcesName = resourcesName;
_assembly = assembly;
_resources = new Lazy(CreateResourceSet, LazyThreadSafetyMode.ExecutionAndPublication);
}
public IDisposable BeginScope()
{
var previous = LazyAssemblyLoaderState.Loader.Value;
LazyAssemblyLoaderState.Loader.Value = this;
return new ScopeDisposer { Previous = previous };
}
public string GetString(string name)
{
return _resources.Value.GetString(name);
}
private ResourceSet CreateResourceSet()
{
var stream = _assembly.GetManifestResourceStream(_resourcesName + ".resources.dll");
return stream == null ? null : new ResourceSet(stream);
}
private class ScopeDisposer : IDisposable
{
public LazyAssemblyLoader Previous { get; set; }
public void Dispose()
{
LazyAssembly
