一个容易忽略的问题-- 调用ServiceDescriptionImporter出错
2012-04-23 11:32 Eric.Hu 阅读(1845) 评论(0) 编辑 收藏 举报最近在研究动态调用WEBService的方法,其中一个地方要用到ServiceDescriptionImporter
System.Web.Services.Description.ServiceDescriptionImporter
命名空间: System.Web.Services.Description
程序集: System.Web.Services(在 System.Web.Services.dll 中)
问题在于我已经添加了System.Web.Services.Description的引用,但编辑器依然无法识别该类,我用的是vs2010,.net framework 4.0;
查找问题,跟踪问题,结果发现问题在我用的是.net framework 4.0 client profile,更改为.net framework 4.0 问题就处理了.
符ServiceDescriptionImporter使用参考:
1 using System; 2 using System.Web.Services.Description; 3 using System.CodeDom; 4 using System.CodeDom.Compiler; 5 using System.Security.Permissions; 6 7 public class Import { 8 9 public static void Main() 10 { 11 Run(); 12 } 13 14 [PermissionSetAttribute(SecurityAction.Demand, Name = "Full Trust")] 15 public static void Run() 16 { 17 // Get a WSDL file describing a service. 18 ServiceDescription description = ServiceDescription.Read("service.wsdl"); 19 20 // Initialize a service description importer. 21 ServiceDescriptionImporter importer = new ServiceDescriptionImporter(); 22 importer.ProtocolName = "Soap12"; // Use SOAP 1.2. 23 importer.AddServiceDescription(description,null,null); 24 25 // Report on the service descriptions. 26 Console.WriteLine("Importing {0} service descriptions with {1} associated schemas.", 27 importer.ServiceDescriptions.Count, importer.Schemas.Count); 28 29 // Generate a proxy client. 30 importer.Style = ServiceDescriptionImportStyle.Client; 31 32 // Generate properties to represent primitive values. 33 importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties; 34 35 // Initialize a Code-DOM tree into which we will import the service. 36 CodeNamespace nmspace = new CodeNamespace(); 37 CodeCompileUnit unit = new CodeCompileUnit(); 38 unit.Namespaces.Add(nmspace); 39 40 // Import the service into the Code-DOM tree. This creates proxy code 41 // that uses the service. 42 ServiceDescriptionImportWarnings warning = importer.Import(nmspace,unit); 43 44 if (warning == 0) 45 { 46 // Generate and print the proxy code in C#. 47 CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp"); 48 provider.GenerateCodeFromCompileUnit(unit, Console.Out, new CodeGeneratorOptions() ); 49 } 50 else 51 { 52 // Print an error message. 53 Console.WriteLine(warning); 54 } 55 } 56 57 58 }
着意耕耘,自有收获。
