调用后Webservices
,返回一个对象(该对象为自定义对象类)给客户端。所以,我想从这个对象转换为自定义类。
-网页服务:
[WebMethod]
public Cls_ROLES GetRoles(int firstNum)
{
Cls_ROLES o = new Cls_ROLES();
o.Role_ID = 2;
o.RoleName = "binh";
return o;
}

+功能:
public object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args)
{
System.Net.WebClient client = new System.Net.WebClient();
//-Connect To the web service
using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl"))
{
//--Now read the WSDL file describing a service.
ServiceDescription description = ServiceDescription.Read(stream);
///// LOAD THE DOM /////////
//--Initialize a service description importer.
ServiceDescriptionImporter importer = new ServiceDescriptionImporter();
importer.ProtocolName = "Soap12"; // Use SOAP 1.2.
importer.AddServiceDescription(description, null, null);
//--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client;
//--Generate properties to represent primitive values.
importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties;
//--Initialize a Code-DOM tree into which we will import the service.
CodeNamespace nmspace = new CodeNamespace();
CodeCompileUnit unit1 = new CodeCompileUnit();
unit1.Namespaces.Add(nmspace);
//--Import the service into the Code-DOM tree. This creates proxy code
//--that uses the service.
ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1);
if (warning == 0) //--If zero then we are good to go
{
//--Generate the proxy code
CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp");
//--Compile the assembly proxy with the appropriate references
string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" };
CompilerParameters parms = new CompilerParameters(assemblyReferences);
CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1);
//-Check For Errors
if (results.Errors.Count > 0)
{
StringBuilder sb = new StringBuilder();
foreach (CompilerError oops in results.Errors)
{
sb.AppendLine("========Compiler error============");
sb.AppendLine(oops.ErrorText);
}
throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString());
}
//--Finally, Invoke the web service method
Type foundType = null;
Type[] types = results.CompiledAssembly.GetTypes();
foreach (Type type in types)
{
if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol))
{
Console.WriteLine(type.ToString());
foundType = type;
}
}
object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString());
MethodInfo mi = wsvcClass.GetType().GetMethod(methodName);
object o = new object();
o=mi.Invoke(wsvcClass, args);
return o;
}
else
{
return null;
}
}
}
+Page_Load 函数:
Line 1:object[] args=new object[1];
Line 2:args[0]=1;
Line 3:o = this.CallWebService("http://localhost:1814/HelloServices/Service.asmx", "Hello", "GetRoles", args);
它在 Line3 处返回一个对象(该对象是一个自定义对象类)给客户端。所以,我想从这个对象转换为自定义类(Cls_Role 对象)。//================================================= =======================================//========== ==================================================== ===========================//====================== ==================================================== ============== 作为 Selalu_Ingin_Belajar 的回答,我可以从 web 服务中获得价值给客户端。
对象你的对象 = 新对象();
foreach (PropertyInfo property in yourObject.GetType().GetProperties())
{
object value = property.GetValue(yourObject , null);
Console.WriteLine("{0} = {1}", property.Name, value);
}
除此之外,当我申请另一个项目时,它显示另一个错误:参数计数不匹配。如果我通过 VisualStudio 工具使用 AddWebReference。它会自动生成 Reference.cs 文件。它包含:
/// <remarks/>
[System.Web.Services.Protocols.SoapRpcMethodAttribute("", RequestNamespace="urn:ALBAPI", ResponseNamespace="urn:ALBAPI")]
[return: System.Xml.Serialization.SoapElementAttribute("info")]
public ResponseInfo getSetupLicenseRows(out SetupLicenseRowsValues values) {
object[] results = this.Invoke("getSetupLicenseRows", new object[0]);
values = ((SetupLicenseRowsValues)(results[1]));
return ((ResponseInfo)(results[0]));
}
因此,通过传递一个对象 SetupLicenseRowsValues 类可以很容易地从 webClient 调用。现在,我必须手动将参数传递给 WebServices。不要使用这个生成文件。

foreach (PropertyInfo property in sSessionID.GetType().GetProperties())

现在,它在线路错误处显示错误“参数计数不匹配”。还是要谢谢你的帮助
