Filter is a comma-delimited list of (Name)(Operator)(Value) in string format where:

  • (Name) is the name of a property with the DTO attribute.

  • (Operator) is one of the operators (see list below).

  • (Value) is the value to use for comparing and filtering.

It's possible to concatenate many (Name)(Operator)(Value) combinations using comma as a separator (Eg:"Id>1,Name@=Test")
Comma separator means an AND operator between the combinations to be evaluated while filtering.

It's also possible to add many options for values using a pipe as a separator (Eg:"Id==1|2|3")
Pipe separator means an OR operator between the values compared to the property while filtering.

Date-time values considerations:

Valid formats:

  • YYYY/MM/DD HH:mm:ss.dddd

  • YYYY.MM.DD HH:mm:ss.dddd

  • YYYY-MM-DD HH:mm:ss.dddd

  • MM/DD/YYYY HH:mm:ss.dddd

  • MM.DD.YYYY HH:mm:ss.dddd

  • MM-DD-YYYY HH:mm:ss.dddd

Whenever a value doesn´t have time, will be considered as 00:00:00:0000
If the same date-time is intended to be included in a range as a result, the from and to values should contain tenths of a second precision (Eg:"Date>=2020/01/01 15:00:00.000,Date<=2020/12/31 23:59:59.9999")

"FloorId==153,Name!@=00,Number_=0008"

Retrieve DTOs wich have FloorId equal to 153 and Name not containing "00" and Number starts with "0008".

"Name>=0005,Number<7,Description@=S|e,Description!_=*e,Id!=258"

Retrieve DTOs wich have their Name greater than or equal to "0005" string comparisson and Number less than 7 and Description contains "S" or contains "e" and Description does not start with "e" comparing case-insensitive and Id is not equal to 258.
