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);
    }
}

获取WebService中的所有web 方法

#region 获取web方法
/// <summary>

/// 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

{
    className = GetClassNameFromUrl(url);
    CompilerResults result = UrlToDllFile(url);
    Assembly assembly = result.CompiledAssembly;
    Type type = assembly.GetType(className);
    return GetWebMethods(type);
}

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)
