C#调用webservice服务有多种方法，下面介绍一种通用的动态调用方法:
一、工具类
class WSHelper
{
/// < summary>
/// 动态调用web服务
/// < /summary>
/// < param name="url">WSDL服务地址< /param>
/// < param name="classname">类名< /param>
/// < param name="methodname">方法名< /param>
/// < param name="namespace">命名空间< /param>
/// < param name="args">参数< /param>
/// < returns>< /returns>
public static object InvokeWebService(string url, string classname, string methodname, string @namespace, object[] args)
{
if ((classname == null) || (classname == ""))
{
classname = WSHelper.GetWsClassName(url.Replace("?wsdl", ""));
}
try
{ //获取WSDL
WebClient wc = new WebClient();
Stream stream = wc.OpenRead(url);
ServiceDescription sd = ServiceDescription.Read(stream);
ServiceDescriptionImporter sdi = new ServiceDescriptionImporter();
sdi.AddServiceDescription(sd, "", "");
CodeNamespace cn = new CodeNamespace(@namespace);
//生成客户端代理类代码
CodeCompileUnit ccu = new CodeCompileUnit();
ccu.Namespaces.Add(cn);
sdi.Import(cn, ccu);
CSharpCodeProvider icc = new CSharpCodeProvider();
//设定编译参数
CompilerParameters cplist = new CompilerParameters();
cplist.GenerateExecutable = false;
cplist.GenerateInMemory = true;
cplist.ReferencedAssemblies.Add("System.dll");
cplist.ReferencedAssemblies.Add("System.XML.dll");
cplist.ReferencedAssemblies.Add("System.Web.Services.dll");
cplist.ReferencedAssemblies.Add("System.Data.dll");
//编译代理类
CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu);
if (true == cr.Errors.HasErrors)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors)
{
sb.Append(ce.ToString());
sb.Append(System.Environment.NewLine);
}
throw new Exception(sb.ToString());
}
//生成代理实例，并调用方法
System.Reflection.Assembly assembly = cr.CompiledAssembly;
Type t = assembly.GetType(@namespace "." classname, true, true);
object obj = Activator.CreateInstance(t);
System.Reflection.MethodInfo mi = t.GetMethod(methodname);
object aa = mi.Invoke(obj, args);
return aa;
}
catch (Exception ex)
{
object str = ex.Message;
return str;
}
}
private static string GetWsClassName(string wsUrl)
{
string[] parts = wsUrl.Split('/');
string[] pps = parts[parts.Length - 1].Split('.');
return pps[0];
}
}
二、调用
String url="http://192.168.9.188:9230/interface?wsdl";
String method ="operat";
String namespace = "DynamicWebCalling";
object[] inPut = new object[] { "入参" };
WSHelper.InvokeWebService(url,null, method, namespace,inPut);
