Implements

 

constructor    (declared in Object)

Default constructor.

 

constructor

 

DbDataReader()

 

init()

 

DbDataReader()

Dispose  virtual abstract

Dispose this object.

 

method Dispose

 

void Dispose()

 

func Dispose()

 

void Dispose()

Equals  virtual    (declared in Object)

Returns true if the target object matches this one, by default compares the reference.

 

method Equals(obj: Object): Boolean

 

Boolean Equals(Object obj)

 

func Equals(_ obj: Object) -> Boolean

 

Boolean Equals(Object obj)

Parameters:

  • obj: the reference to compare this with.

FieldCount  virtual

Contains the number of fields.

 

property FieldCount: Int32 read;

 

Int32 FieldCount { get; }

 

var FieldCount: Int32 { get{} }

 

Int32 FieldCount { __get; }

FieldName  virtual

Contains the field names from this query, accessible by index.

 

property FieldName[i: Int32]: String read;

 

String FieldName[Int32 i] { get; }

 

subscript FieldName(_ i: Int32) -> String { get{} }

 

String FieldName[Int32 i] { __get; }

Finalize  protected virtual    (declared in Object)

Finalizer implementation. If not overriden it's not called at all, the runtime checks if there is an override before calling a finalizer.

 

method Finalize

 

void Finalize()

 

func Finalize()

 

void Finalize()

GetHashCode  virtual    (declared in Object)

Returns a hashcode for this object. Overriden implementations should make sure that the number returned here is constant given the same object.

 

method GetHashCode: Int32

 

Int32 GetHashCode()

 

func GetHashCode() -> Int32

 

Int32 GetHashCode()

GetType    (declared in Object)

Returns the actual type of this class

 

method GetType: Type

 

Type GetType()

 

func GetType() -> Type

 

Type GetType()

Item  virtual

Returns the values in this row. Note that the reader is "before" the first row, call Read/ReadAsync first.

 

property Item[i: Int32]: Object read;

 

Object Item[Int32 i] { get; }

 

subscript Item(_ i: Int32) -> Object { get{} }

 

Object Item[Int32 i] { __get; }

Read  virtual abstract

Retrieves the next row, returns true if succesful, false if the end of the dataset has been reached. By default the reader is set before the first row, so the first call should always be to Read.

 

method Read: Boolean

 

Boolean Read()

 

func Read() -> Boolean

 

Boolean Read()

ReadAsync  virtual

Retrieves the next row, returns true if succesful, false if the end of the dataset has been reached. By default the reader is set before the first row, so the first call should always be to Read.

 

method ReadAsync: Task<Boolean>

 

Task<Boolean> ReadAsync()

 

func ReadAsync() -> Task<Boolean>

 

Task<Boolean> ReadAsync()

ReferenceEquals    (declared in Object)

Compares two references for equivalence (even if they have an equals operator)

 

class method ReferenceEquals(a: Object; b: Object): Boolean

 

static Boolean ReferenceEquals(Object a, Object b)

 

static func ReferenceEquals(_ a: Object, _ b: Object) -> Boolean

 

static Boolean ReferenceEquals(Object a, Object b)

Parameters:

  • a: left value
  • b: right value

ToString  virtual    (declared in Object)

Gets the string representation of this method.

 

method ToString: String

 

String ToString()

 

func ToString() -> String

 

String ToString()

 

FieldCount  virtual

property FieldName[i: Int32]: String read;

 

String FieldName[Int32 i] { get; }

 

subscript FieldName(_ i: Int32) -> String { get{} }

 

String FieldName[Int32 i] { __get; }
