先学生成,再看调用哦
【超细完整版】C# 获取WebService所有方法并调用 【调用篇】
支持通过web url (自适应“?wsdl”的有无) 生成.wsdl文件 和 .dll文件
将通过一个类的三部分来实现这些功能
类名为 WebServiceHelper.cs
/// /// 动态调用WebService(支持SaopHeader) /// public class WebServiceHelper { } 并在该类实现下述方法
#region 获取url中的ClassName /// /// 获取WebService的类名 /// /// WebService地址 /// 返回WebService的类名 public static string GetClassNameFromUrl(string wsUrl) { string result = string.Empty; if (!wsUrl.EndsWith("?wsdl", StringComparison.CurrentCultureIgnoreCase)) { wsUrl = wsUrl + "?wsdl"; } XmlDocument doc = new XmlDocument(); doc.Load(wsUrl); try { result = doc.GetElementsByTagName("wsdl:service")[0].Attributes[0].Value; } catch (Exception err) { return string.Empty; } return result; } #endregion #region 生成WSDL public static void UrlToWsdlFile(string url, string savePath, string outName = "") { string className = string.Empty; string FullFileName = string.Empty; className = GetClassNameFromUrl(url); if (outName == "") { outName = className + ".wsdl"; } else { if (!outName.EndsWith(".wsdl", StringComparison.CurrentCultureIgnoreCase)) { outName = outName + ".wsdl"; } } if (!url.EndsWith("?wsdl", StringComparison.CurrentCultureIgnoreCase)) { url = url + "?wsdl"; } FullFileName = savePath + "\\" + outName; WebClient wc = new WebClient(); if (!System.IO.Directory.Exists(savePath)) { System.IO.Directory.CreateDirectory(savePath);//不存在就创建文件夹 } wc.DownloadFile(url, FullFileName); } #endregion #region 生成DLL public static CompilerResults UrlToDllFile(string url, string @namespace = "") { string className = string.Empty; className = GetClassNameFromUrl(url); if (!url.EndsWith("?wsdl", StringComparison.CurrentCultureIgnoreCase)) { url = url + "?wsdl"; } WebClient web = new WebClient(); Stream stream = web.OpenRead(url); //创建和格式化 WSDL 文档。 ServiceDescription description = ServiceDescription.Read(stream); CompilerResults compiler = CreatDll(className, description, @namespace); return compiler; } private static CompilerResults CreatDll(string className, ServiceDescription description, string @namespace = "") { try { // 3. 创建客户端代理代理类。 ServiceDescriptionImporter importer = new ServiceDescriptionImporter(); // 指定访问协议。 importer.ProtocolName = "Soap"; // 生成客户端代理。 importer.Style = ServiceDescriptionImportStyle.Client; importer.CodeGenerationOptions = CodeGenerationOptions.GenerateProperties | CodeGenerationOptions.GenerateNewAsync; // 添加 WSDL 文档。 importer.AddServiceDescription(description, null, null); // 4. 使用 CodeDom 编译客户端代理类。 // 为代理类添加命名空间,缺省为全局空间。 CodeNamespace nmspace = new CodeNamespace(); nmspace.Name = @namespace; CodeCompileUnit unit = new CodeCompileUnit(); unit.Namespaces.Add(nmspace); ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit); CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp"); CompilerParameters parameter = new CompilerParameters(); parameter.GenerateExecutable = false; parameter.GenerateInMemory = true;//在内存中生成输出 // 可以指定你所需的任何文件名。 parameter.OutputAssembly = AppDomain.CurrentDomain.BaseDirectory + "dll\\" + className + ".dll"; parameter.ReferencedAssemblies.Add("System.dll"); parameter.ReferencedAssemblies.Add("System.XML.dll"); parameter.ReferencedAssemblies.Add("System.Web.Services.dll"); parameter.ReferencedAssemblies.Add("System.Data.dll"); // 生成dll文件,并会把WebService信息写入到dll里面 CompilerResults result = provider.CompileAssemblyFromDom(parameter, unit); if (result.Errors.HasErrors) { System.Text.StringBuilder sb = new System.Text.StringBuilder(); foreach (System.CodeDom.Compiler.CompilerError ce in result.Errors) { sb.Append(ce.ToString()); sb.Append(System.Environment.NewLine); } throw new Exception(sb.ToString()); } return result; } catch (Exception err) { MessageBox.Show(err.Message, "Error"); return null; } } #endregion 个人示例,实际根据自己需求调整 ; 以下为窗体按钮事件
private void bt_generate_dll_Click(object sender, EventArgs e) { try { WebServiceHelper.UrlToDllFile(tb_webLink.Text); if (MessageBox.Show("The dll is generated successfully. Do you want to open the file path?", "notice", MessageBoxButtons.YesNo) == DialogResult.Yes) openPath("dll"); } catch (Exception err) { MessageBox.Show(err.Message, "Error"); } } private void openPath(string type) { if (string.IsNullOrEmpty(type)) return; string key = string.Empty; key = type.Equals(defaultKey) ? wsdlPathKey : dllPathKey; //get Configuration object Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); //get value by key string path = config.AppSettings.Settings[key].Value; System.Diagnostics.Process.Start("explorer.exe", path); }
