开始

首先实现一个类，用于实现对URL的验证等

public class InputFormatVerification
{/// <summary>/// 是否合法Url地址（统一资源定位）/// </summary>/// <param name="strValue">url地址</param>/// <returns>成功返回true 失败返回false</returns>public static bool IsUrl(string strValue){string RegexStr = string.Empty;RegexStr = @"^(http|https)\://([a-zA-Z0-9\.\-]+(\:[a-zA-Z0-9\.&%\$\-]+)*@)*((25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])|localhost|([a-zA-Z0-9\-]+\.)*[a-zA-Z0-9\-]+\.(com|edu|gov|int|mil|net|org|biz|arpa|info|name|pro|aero|coop|museum|[a-zA-Z]{1,10}))(\:[0-9]+)*(/($|[a-zA-Z0-9\.\,\?\'\\\+&%\$#\=~_\-]+))*$";return formatChecks(RegexStr, strValue);}/// <summary>/// 检测串值是否为合法的格式/// </summary>/// <param name="strRegex">正则表达式</param>/// <param name="strValue">要检测的String值</param>/// <returns>成功返回true 失败返回false</returns>public static bool formatChecks(string strRegex, string strValue){if (string.IsNullOrWhiteSpace(strValue)){return false;}Regex re = new Regex(strRegex);return re.IsMatch(strValue);}
}

实现Invoke

获取WebService中的所有web 方法

#region 获取web方法
/// <summary>
/// 获取WebService接口的所有WebMethod方法
/// 通过WebService方法的特性为【System.Web.Services.Protocols.SoapDocumentMethodAttribute】
/// 根据特性SoapDocumentMethodAttribute来筛选出所有WebMethod方法
/// </summary>
/// <param name="url"></param>
public static List<MethodInfo> GetAllWebMethodsFromLink(string url, out string className)
{className = GetClassNameFromUrl(url);CompilerResults result = UrlToDllFile(url);Assembly assembly = result.CompiledAssembly;Type type = assembly.GetType(className);return GetWebMethods(type);
}
/// <summary>
/// 获取WebService接口的所有WebMethod方法
/// 通过WebService方法的特性为【System.Web.Services.Protocols.SoapDocumentMethodAttribute】
/// 根据特性SoapDocumentMethodAttribute来筛选出所有WebMethod方法
/// </summary>
/// <param name="wsdlFilePath"></param>
public static List<MethodInfo> GetAllWebMethodsFromWsdl(string wsdlFilePath, out string className)
{className = GetClassNameFromWsdl(wsdlFilePath);CompilerResults result = WsdlToDll(wsdlFilePath);Assembly assembly = result.CompiledAssembly;Type type = assembly.GetType(className);return GetWebMethods(type);
}private static List<MethodInfo> GetWebMethods(Type type)
{List<MethodInfo> methodInfoList = new List<MethodInfo>();if (type == null){return methodInfoList;}MethodInfo[] methodInfos = type.GetMethods();for (int i = 0; i < methodInfos.Length; i++){MethodInfo methodInfo = methodInfos[i];//WebMethod方法的特性为：System.Web.Services.Protocols.SoapDocumentMethodAttribute Attribute attribute = methodInfo.GetCustomAttribute(typeof(System.Web.Services.Protocols.SoapDocumentMethodAttribute));if (methodInfo.MemberType == MemberTypes.Method && attribute != null){methodInfoList.Add(methodInfo);}}return methodInfoList;
}
#endregion

通过wsdl或url进行调用

/// <summary>
/// 调用WebService
/// </summary>
/// <param name="address">WebService地址</param>
/// <param name="methodName">方法名称</param>
/// <param name="args">参数列表</param>
/// <param name="timeOut"></param>
/// <returns>返回调用结果</returns>
/// <exception cref="Exception"></exception>
private static object InvokeWebService(string address, string methodName, object[] args, string timeOut = "")
{try{string className = string.Empty;CompilerResults result = null;//支持直接URL或wsdl类型文件的调用if (InputFormatVerification.IsUrl(address)){className = GetClassNameFromUrl(address);result = UrlToDllFile(address);}else{className = GetClassNameFromWsdl(address);result = WsdlToDll(address);}Assembly assembly = result.CompiledAssembly;Type type = assembly.GetType(className);FieldInfo[] arry = type.GetFields();//实例类型对象   object obj = Activator.CreateInstance(type);System.Reflection.MethodInfo mi = type.GetMethod(methodName);//添加超时时间if (!string.IsNullOrEmpty(timeOut)){int timeout = 0;int.TryParse(timeOut, out timeout);if (timeout == 0) timeout = 1200;//设置超时时间((System.Web.Services.Protocols.WebClientProtocol)(obj)).Timeout = timeout * 1000;//毫秒s,timeOut超时时间设置为分钟}var res = mi.Invoke(obj, args);return res;}catch (Exception ex){throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace));}
