Remarks

To perform this action, the caller must be a user in the organization for which metadata is requested and must have Read Attribute, Read Entity and Read Relationship privileges.

Example

The following example shows how to use the CanManyToMany message.

// Create an authentication token.
CrmAuthenticationToken token = new CrmAuthenticationToken();
token.OrganizationName = "AdventureWorksCycle";

// You can use enums.cs from the SDK\Helpers folder to get the enumeration for Active Directory authentication.
token.AuthenticationType = 0; 

// Create the metadata Web service.
MetadataService metadataService = new MetadataService();
metadataService.Url = "http://<servername>:<port>/MSCRMServices/2007/MetadataService.asmx";
metadataService.CrmAuthenticationTokenValue = token;
metadataService.Credentials = System.Net.CredentialCache.DefaultCredentials;
metadataService.PreAuthenticate = true;

// Create the request.
CanManyToManyRequest validManyEntityRequest = new CanManyToManyRequest();
validManyEntityRequest.EntityName = EntityName.account.ToString();

// Execute the request.
CanManyToManyResponse validManyEntityResponse = (CanManyToManyResponse)metadataService.Execute(validManyEntityRequest);

// Determine if the Account entity can participate in a many-to-many relationship.
bool bAccountIsValid = validManyEntityResponse.CanManyToMany;
[Visual Basic .NET]
' Set up the CRM service.
Dim token As 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";

// Create the metadata Web service.
Dim metadataService As New MetadataService ()
metadataService.Url = "http://<servername>:<port>/mscrmservices/2007/MetadataService.asmx";
metadataService.CrmAuthenticationTokenValue = token;
metadataService.Credentials = System.Net.CredentialCache.DefaultCredentials
metadataService.PreAuthenticate = true;

' Create the request.
Dim validManyEntityRequest As New CanManyToManyRequest()
validManyEntityRequest.EntityName = EntityName.account.ToString()

' Execute the request.
Dim validManyEntityResponse As CanManyToManyResponse = CType(metadataService.Execute(validManyEntityRequest), CanManyToManyResponse)

' Determine if the Account entity can participate in a many-to-many relationship.
Dim bAccountIsValid As Boolean = validManyEntityResponse.CanManyToMany
