使用 XUnit 和 Asp.Net Core 5 我有以下测试:
public class Tests : IClassFixture<ServiceProviderFixture> {
private readonly ServiceProviderFixture _fixture;
public IndicatorsTests(ServiceProviderFixture fixture) {
_fixture = fixture;
}
[Fact]
public async Task FirstTest() {
IEnumerable<Decimal> values = await _fixture.Provider.GetService<ICsvImporter>().ImportAsync("Values.csv");
Assert.Equal(1000, values.Count());
}
}

ServiceProviderFixture类是:public class ServiceProviderFixture : IDisposable {
public IServiceProvider Provider { get; private set; }
public ServiceProviderFixture() {
IServiceCollection services = new ServiceCollection();
services.AddSingleton<CsvImporterConfiguration>();
services.AddTransient<ICsvImporter, CsvImporter>();
Provider = services.BuildServiceProvider();
}
public void Dispose() { } // Dispose
}
CsvImporter类是:public class CsvImporter : ICsvImporter {
private readonly CsvImporterConfiguration _configuration;
public CsvImporter(CsvImporterConfiguration configuration) {
_configuration = configuration;
}
public CsvImporter(Action<CsvImporterConfiguration> configuration) {
_configuration = new CsvImporterConfiguration();
configuration(_configuration);
}
public async Task<IEnumerable<Decimal>> ImportAsync(String path, CancellationToken token = default(CancellationToken)) {
return await Task.Factory.StartNew(() => {
using (StreamReader stream = new StreamReader(path)) {
using (CsvReader csv = new CsvReader(stream, new CsvConfiguration(_configuration.Culture) {
Delimiter = _configuration.Delimiter
})) {
return csv.GetRecords<Decimal>();
}
}
}, token);
}
}
也许从文件中读取？
最佳答案
这是 MacOS 上的一个已知问题。
安装防病毒软件时似乎最常发生。

我见过好几个这样的案例。我发现的唯一“修复”是卸载防病毒软件。在某些情况下，我们不得不重新安装 MacOS。
如果您使用的不是 MacOS，请告诉我们。
关于c# - 运行 MSBuild 时发生内部故障 - 无法加载文件或程序集 System.Net.Primitives，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/67541011/
