Sets the state of an opportunity to Lost

Sets the state of an opportunity to Lost.

//# The following code example shows how to use the LoseOpportunity message.
// Set up the CRM service.

// You can use enums.cs from the SDK\Helpers folder to get the enumeration for Active Directory authentication.

Reflection

Reflection provides objects (of type Type) that encapsulate assemblies, modules and types. You can use reflection to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties. If you are using attributes in your code, Reflection enables you to access them.

Here's a simple example of Reflection using the static method GetType - inherited by all types from the Object base class - to obtain the type of a variable:

 
// Using GetType to obtain type information:
int i = 42;
System.Type type = i.GetType();
System.Console.WriteLine(type);
 

In this example, Reflection is used to obtain the full name of a loaded assembly:

 
// Using Reflection to get information from an Assembly:
System.Reflection.Assembly o = System.Reflection.Assembly.Load("mscorlib.dll");
System.Console.WriteLine(o.GetName());
  

The output is:

mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

ImportCompressedAllXml Message

Import all customizations from an XML file that has been compressed using the WinZip format.

 
This request requires an ImportExportXml file for import. This example exports this file from CRM and then imports it back into Microsoft Dynamics CRM.
[C#]
// Set up the CRM service.
CrmAuthenticationToken token = new CrmAuthenticationToken();
// You can use enums.cs from the SDK\Helpers folder to get the enumeration for Active Directory authentication.
token.AuthenticationType = 0; 
token.OrganizationName = "AdventureWorksCycle";
 
CrmService service = new CrmService();
service.Url = "http://:/mscrmservices/2007/crmservice.asmx";
service.CrmAuthenticationTokenValue = token;
service.Credentials = System.Net.CredentialCache.DefaultCredentials;

// Create the request.
ExportCompressedAllXmlRequest requestExport = new ExportCompressedAllXmlRequest();
requestExport.EmbeddedFileName = "customizations.xml";

// Execute the request.
ExportCompressedAllXmlResponse responseExport = (ExportCompressedAllXmlResponse)service.Execute(requestExport);

// Get the compressed data
byte[] compressedXML = responseExport.ExportCompressedXml;

// Create the request.
ImportCompressedAllXmlRequest request = new ImportCompressedAllXmlRequest();

// Assign the compressed data
request.CompressedCustomizationXml = compressedXML;

// Execute the request.
ImportCompressedAllXmlResponse response = (ImportCompressedAllXmlResponse)service.Execute(request);
