如何在 Dynamics 365 C# 插件中查询用户的团队？

Question

The example shown here passes in the userID and a string array of security names. Then return true if the user has any security roles that match the names.

public static bool UserHasRoles(IOrganizationService service, Guid userId, params string[] roleNames)
{
        var query = new QueryExpression("systemuserroles");
        query.TopCount = 1; 
        query.ColumnSet.AddColumns("systemuserroleid");           
        query.Criteria.AddCondition("systemuserid", ConditionOperator.Equal, userId);
        
        var query_role = query.AddLink("role", "roleid", "roleid");            
        query_role.LinkCriteria.AddCondition("name", ConditionOperator.In, roleNames);
        
        var result = service.RetrieveMultiple(query);
        return result.Entities.Any();
}

I need to recreate this code but to return true if the user is part of any teams that contain the same names. Below is my attempt:

public static bool UserHasRoles(IOrganizationService service, Guid userId, params string[] roleNames)
{
        var query = new QueryExpression("teammembership");
        query.TopCount = 1; 
        query.ColumnSet.AddColumns("teamMembershipId");           
        query.Criteria.AddCondition("systemuserid", ConditionOperator.Equal, userId);

        var query_role = query.AddLink("team", "teamid", "teamid");
        query_role.LinkCriteria.AddCondition("name", ConditionOperator.In, roleNames);
        
        var result = service.RetrieveMultiple(query);

        return result.Entities.Any();
}

When ran the code, I get an error

'TeamMembership' entity doesn't contain attribute with Name = 'teamMembershipId' and NameMapping = 'Logical'

I'm unsure if I am querying the equivalent entity correctly. Or I may be going about this in completely the wrong way. Help would be great.

Actually, you don't need any column to be returned.
Here's your code without ColumnSet line, also I've corrected your method name and parameter name:

public static bool UserInTeams(IOrganizationService service, Guid userId, params string[] teamNames)
{
    var query = new QueryExpression("teammembership");
    query.TopCount = 1;
    query.Criteria.AddCondition("systemuserid", ConditionOperator.Equal, userId);
    
    var query_role = query.AddLink("team", "teamid", "teamid");
    query_role.LinkCriteria.AddCondition("name", ConditionOperator.In, teamNames);
    
    var result = service.RetrieveMultiple(query);
    return result.Entities.Any();
}
