personId uniqueidentifier

public IQueryable<Report_person>GetPerson(uniqueidentifier personId)

Thanks.

Usually uniqueidentifier corresponds with System.Guid, as listed in SqlDbType.

Depends on what your uniqueidentifier is. C# has a Guid class that is used for globally unique identifiers, or if this is for a database and you have just an incremental ID number as the identifier and int would be fine. Depends on how you are creating the ID and what you are using it for, but usually a unique Identifier in C# is represented by a Guid or Globally Unique Identifier

Guid uniqueId = Guid.NewGuid();

public IQueryable<Report_person>GetPerson(Guid personId) {}
