Question

我有一个接口和一个实现它的类。我正在尝试创建一个单元测试，它将编译接口和类，并查看是否有任何错误（如果没有那么那将意味着该类确实实现了接口）。我能够构建没有错误的接口，但是当我尝试构建实现它的类时，它表示该类没有实现接口。我已经确定该类确实实现了接口，所以我知道我在单元测试中编译它的方式有问题。我生成inMemoryAssembly.dll，然后在尝试编译实现时尝试将其添加到参数中，但这不起作用。有什么建议吗？

            var serviceReferancepath = System.IO.Path.GetFullPath(@"..\..\Service References\");
            compileIterface(serviceReferancepath);
            compileImplementation(serviceReferancepath);
        }

                // Read and display lines from the file until the end of 
                // the file is reached.
                while ((line = sr.ReadLine()) != null)
                {
                    implementationSC.AppendLine(line);
                }
            }
            CompilerResults results = compiler.CompileAssemblyFromSource(Parameters, implementationSC.ToString());
            StringWriter sw = new StringWriter();
            foreach (CompilerError ce in results.Errors)
            {
                if (ce.IsWarning) continue;
                sw.WriteLine("{0}({1},{2}: error {3}: {4}", ce.FileName, ce.Line, ce.Column, ce.ErrorNumber, ce.ErrorText);
            }
            // If there were errors, raise an exception...
            string errorText = sw.ToString();
        }

    }
}

compileImplementation方法，当我用断点运行它时，我得到结果的以下错误 UnitTestProject2.alarm.ActiveEventSource'没有实现接口成员'UnitTestProject2.alarm.IActiveEventSource.EventSource

这是实现代码

namespace UnitTestProject2.alarm
{
    partial class ActiveEventSource: IActiveEventSource
    {
    }
}

编辑：我正在查看警告，但没有查看实现编译所说的实际错误。 compileImplementatation方法的字符串errortext表示无法找到inMemoryAssembly.dll

使用从ICode编译器生成的内存程序集来构建另一个源代码
