如何使用CodeDom创建一个接口方法

我正在使用CodeDom生成我的WCF服务接口和实现文件。 我在CodeMemberMethod上找不到任何可以生成接口方法的选项。 如果我使用MemberAttributes.Abstract，我几乎就在那里，但它包含对接口无效的abstract关键字。 有谁知道生成方法的正确语法？

这是我为生成接口文件而开发的代码：private void CreateServiceContractFile（Type entity，BoElement bo，DirectoryInfo serviceOutputDir，AppParameters appPrams）{CodeCompileUnit serviceFileUnit = new CodeCompileUnit（）;

CodeNamespace importNameSpace = new CodeNamespace(""); importNameSpace.Imports.Add(new CodeNamespaceImport("System")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Collections.Generic")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Linq")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Runtime.Serialization")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.ServiceModel")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.ServiceModel.Web")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Text")); importNameSpace.Imports.Add(new CodeNamespaceImport("ALVIN.BusinessObjects")); importNameSpace.Imports.Add(new CodeNamespaceImport("DAOObjects = ALVIN.DAO")); importNameSpace.Imports.Add(new CodeNamespaceImport("ALIAS.BusinessObjects")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Data.Entity.Validation")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.ComponentModel.DataAnnotations")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Data.Objects")); importNameSpace.Imports.Add(new CodeNamespaceImport("ALIAS.Common.Utility")); importNameSpace.Imports.Add(new CodeNamespaceImport("ALIAS.EventMessages")); importNameSpace.Imports.Add(new CodeNamespaceImport("ALIAS.ServiceCommon")); importNameSpace.Imports.Add(new CodeNamespaceImport(appPrams.BoNameSpace)); serviceFileUnit.Namespaces.Add(importNameSpace); string serviceName = string.Format("{0}Service", entity.Name); CodeTypeDeclaration serviceClass = new CodeTypeDeclaration(serviceName); serviceClass.IsClass = true; serviceClass.BaseTypes.Add(new CodeTypeReference("I" + serviceName)); serviceClass.TypeAttributes = TypeAttributes.Public; serviceClass.Comments.AddRange(Helper.CreateComment("The Service Contract class")); CodeParameterDeclarationExpression headerParm = new CodeParameterDeclarationExpression( typeof(ALIASTransactionHeader), "header"); CodeParameterDeclarationExpression requestParm = new CodeParameterDeclarationExpression( bo.BoName, "requestBO"); CodeMemberMethod enterMethod = new CodeMemberMethod(); MethodCommentInfo methodComments = new MethodCommentInfo(); methodComments.CommentSummaryLines.Add(string.Format("Enters a {0} into the system.", bo.BoName)); methodComments.CommentParameters.Add(new ParameterInfo("header", "Security and Logging information for the web method")); methodComments.CommentParameters.Add(new ParameterInfo("requestBO", string.Format("{0} to be entered into the system", bo.BoName))); enterMethod.Comments.AddRange(Helper.CreateMethodComment(methodComments)); enterMethod.Parameters.Add(headerParm); enterMethod.Parameters.Add(requestParm); enterMethod.PrivateImplementationType = new CodeTypeReference("I" + serviceName); //enterMethod.Attributes = MemberAttributes.Public | MemberAttributes.Abstract; enterMethod.Name = string.Format("Enter{0}", bo.BoName); serviceClass.Members.Add(enterMethod); CodeNamespace serviceNameSpace = new CodeNamespace(bo.ServiceNameSpace); serviceNameSpace.Types.Add(serviceClass); serviceFileUnit.Namespaces.Add(serviceNameSpace); Helper.CreateFile(serviceFileUnit, new FileInfo(serviceOutputDir + @"" + serviceName + @".svc.cs")); } 

 var compUnit = new CodeCompileUnit(); var ns = new CodeNamespace("TestNamespace"); var iface = new CodeTypeDeclaration("ITest"); iface.IsInterface = true; var mth = new CodeMemberMethod(); mth.Name = "DoSomething"; mth.ReturnType = new CodeTypeReference(typeof(string)); mth.Parameters.Add(new CodeParameterDeclarationExpression(typeof(int), "x")); iface.Members.Add(mth); ns.Types.Add(iface); compUnit.Namespaces.Add(ns); var csProv = new CSharpCodeProvider(); using (var tw = File.CreateText(@"test.cs")) { var options = new CodeGeneratorOptions(); csProv.GenerateCodeFromCompileUnit(compUnit, tw, options); tw.Flush(); } 

 namespace TestNamespace { public interface ITest { string DoSomething(int x); } }
