Update Account Ownership

With help of this code snippet you can update Account ownership programatically.

TargetOwnedAccount target = new TargetOwnedAccount();
// Account Id for which you want to update ownership
target.EntityId = accountGuid;

systemuser objSystemUser = new systemuser();

// Set SystemUser which you want to set as a owner for account
objSystemUser = (systemuser)becSystemUser.BusinessEntities[0];
SecurityPrincipal assignee = new SecurityPrincipal();
assignee.Type = SecurityPrincipalType.User;

// Set fetched user id which we want to set as owner
assignee.PrincipalId = objSystemUser.systemuserid.Value;

AssignRequest asgRequest = new AssignRequest();
asgRequest.Assignee = assignee;
asgRequest.Target = target;
AssignResponse asgResponse = (AssignResponse)objCRMService.Execute(asgRequest);
