public class DataReader : BinaryReader
The DataReader type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | DataReader |
Construct a new DataReader that will read from a passed
Stream object.
|
Properties| Name | Description | |
|---|---|---|
 | BaseStream | (Inherited from BinaryReader.) |
Methods| Name | Description | |
|---|---|---|
| Close | Closes the current reader and the underlying stream. (Inherited from BinaryReader.) |
| Dispose | (Inherited from BinaryReader.) |
 | Dispose(Boolean) | (Inherited from BinaryReader.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| FillBuffer | (Inherited from BinaryReader.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| PeekChar | (Inherited from BinaryReader.) |
| Read | (Inherited from BinaryReader.) |
| Read(Char, Int32, Int32) | (Inherited from BinaryReader.) |
| Read(Byte, Int32, Int32) | (Inherited from BinaryReader.) |
| Read7BitEncodedInt | (Inherited from BinaryReader.) |
| ReadBoolean | (Inherited from BinaryReader.) |
| ReadByte | (Inherited from BinaryReader.) |
| ReadBytes | (Inherited from BinaryReader.) |
| ReadChar | (Inherited from BinaryReader.) |
| ReadChars | (Inherited from BinaryReader.) |
| ReadDecimal | (Inherited from BinaryReader.) |
| ReadDouble |
Reads bits which are stored in an Int64 instance and
converts them into the Double object.
(Overrides BinaryReaderReadDouble.) |
| ReadInt16 |
Reads a 2-byte signed integer from the current stream and
advances the current position of the stream by two bytes.
(Overrides BinaryReaderReadInt16.) |
| ReadInt32 |
Reads a 4-byte signed integer from the current stream and
advances the current position of the stream by four bytes.
(Overrides BinaryReaderReadInt32.) |
| ReadInt64 |
Reads an 8-byte signed integer from the current stream and
advances the current position of the stream by eight bytes.
(Overrides BinaryReaderReadInt64.) |
| ReadPackedInt32 |
Reads an Int32 value using a variable-length storage
format.
|
| ReadPackedInt64 |
Reads an Int64 value using a variable-length storage
format.
|
| ReadPackedRawInt128 |
Reads a RawInt128 value from DataReader.
|
| ReadSByte | (Inherited from BinaryReader.) |
| ReadSingle |
Reads bits which are stored in an Int32 instance and
converts them into the Single object.
(Overrides BinaryReaderReadSingle.) |
| ReadString |
Reads string from the stream.
(Overrides BinaryReaderReadString.) |
| ReadUInt16 |
Reads a 2-byte unsigned integer from the current stream using
little endian encoding and advances the position of the stream by
two bytes.
(Overrides BinaryReaderReadUInt16.) |
| ReadUInt32 |
Reads a 4-byte unsigned integer from the current stream and
advances the position of the stream by four bytes.
(Overrides BinaryReaderReadUInt32.) |
| ReadUInt64 |
Reads an 8-byte unsigned integer from the current stream and
advances the position of the stream by eight bytes.
(Overrides BinaryReaderReadUInt64.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
RemarksThe "packed" format includes a sign bit (0x40) and a continuation bit (0x80) in the first byte, followed by the least 6 significant bits of the int value. Subsequent bytes (each appearing only if the previous byte had its continuation bit set) include a continuation bit (0x80) and the next least 7 significant bits of the int value.
In this way, a 32-bit value is encoded into 1-5 bytes, and 64-bit value is encoded into 1-10 bytes, depending on the magnitude of the value being encoded.
