【超细完整版】C# WebService 通过URL生成WSDL文件和DLL文件 【生成篇】

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】

目的

支持通过web url (自适应“?wsdl”的有无) 生成.wsdl文件 和 .dll文件

实现

将通过一个类的三部分来实现这些功能

• 获取url中的ClassName （GetClassNameFromUrl）
• 转换为WSDL文件 （UrlToWsdlFile）
• 转换为DLL文件 （UrlToDllFile）

创建一个新类

类名为 WebServiceHelper.cs

    /// <summary>/// 动态调用WebService（支持SaopHeader）/// </summary>public class WebServiceHelper{}

并在该类实现下述方法

获取url中的ClassName

#region 获取url中的ClassName
/// <summary>   
/// 获取WebService的类名   
/// </summary>   
/// <param name="wsUrl">WebService地址</param>   
/// <returns>返回WebService的类名</returns>   
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

转换为WSDL文件

 #region 生成WSDLpublic 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

转换为DLL文件

#region 生成DLLpublic 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

应用

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 objectConfiguration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);//get value by keystring path = config.AppSettings.Settings[key].Value;System.Diagnostics.Process.Start("explorer.exe", path);
}
