I needed something like this some time ago, and I got excellent results with this function:
[System.Security.Permissions.SecurityPermissionAttribute(System.Security.Permissions.SecurityAction.Demand, Unrestricted = true)]
internal static object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args)
{
// Veja http://social.msdn.microsoft.com/Forums/vstudio/en-US/39138d08-aa08-4c0c-9a58-0eb81a672f54/adding-a-web-reference-dynamically-at-runtime?forum=csharpgeneral
System.Net.WebClient client = new System.Net.WebClient();
// Connect To the web service
System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl");
// Now read the WSDL file describing a service.
var description = System.Web.Services.Description.ServiceDescription.Read(stream);
///// LOAD THE DOM /////////
// Initialize a service description importer.
var importer = new System.Web.Services.Description.ServiceDescriptionImporter();
importer.ProtocolName = "Soap12"; // Use SOAP 1.2.
importer.AddServiceDescription(description, null, null);
// Generate a proxy client.
importer.Style = System.Web.Services.Description.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.
var nmspace = new System.CodeDom.CodeNamespace();
var unit1 = new System.CodeDom.CodeCompileUnit();
unit1.Namespaces.Add(nmspace);
// Import the service into the Code-DOM tree. This creates proxy code that uses the service.
var warning = importer.Import(nmspace, unit1);
if (warning == 0) // If zero then we are good to go
{
// Generate the proxy code
var provider1 = System.CodeDom.Compiler.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" };
var parms = new System.CodeDom.Compiler.CompilerParameters(assemblyReferences);
var results = provider1.CompileAssemblyFromDom(parms, unit1);
// Check For Errors
if (results.Errors.Count > 0)
{
foreach (System.CodeDom.Compiler.CompilerError oops in results.Errors)
{
System.Diagnostics.Debug.WriteLine("========Compiler error============");
System.Diagnostics.Debug.WriteLine(oops.ErrorText);
}
throw new System.Exception("Compile Error Occured calling webservice. Check Debug ouput window.");
}
// Finally, Invoke the web service method
object wsvcClass = results.CompiledAssembly.CreateInstance(serviceName);
var mi = wsvcClass.GetType().GetMethod(methodName);
return mi.Invoke(wsvcClass, args);
}
else
{
return null;
}
}
Example of use:
string link = "http://localhost:19656/serviço.asmx";
object[] args = { "teste" };
var ws = CallWebService(link, "MeuServiço", "MeuMetodo", args);
if (ws != null)
{
str = ws.ToString(); // Resultado
}
Exactly what I need! Tks!
