public class DataWriter : BinaryWriter
The DataWriter type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | DataWriter |
Construct a new DataWriter that will write data to the
specified Stream object.
|
Properties| Name | Description | |
|---|---|---|
 | BaseStream | (Inherited from BinaryWriter.) |
Methods| Name | Description | |
|---|---|---|
| Close | Closes the current BinaryWriter and the underlying stream. (Inherited from BinaryWriter.) |
| Dispose | (Inherited from BinaryWriter.) |
 | Dispose(Boolean) | (Inherited from BinaryWriter.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| Flush | (Inherited from BinaryWriter.) |
| 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.) |
| Seek | (Inherited from BinaryWriter.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Write(Boolean) | (Inherited from BinaryWriter.) |
| Write(Byte) | (Inherited from BinaryWriter.) |
| Write(SByte) | (Inherited from BinaryWriter.) |
| Write(Byte) | (Inherited from BinaryWriter.) |
| Write(Char) | (Inherited from BinaryWriter.) |
| Write(Char) | (Inherited from BinaryWriter.) |
| Write(Decimal) | (Inherited from BinaryWriter.) |
| Write(Double) |
Converts a Double value to its bits and writes an Int64 instance
which stores the bits.
(Overrides BinaryWriterWrite(Double).) |
| Write(Int16) |
Writes a two-byte signed integer to the current stream and
advances the stream position by two bytes.
(Overrides BinaryWriterWrite(Int16).) |
| Write(Int32) |
Writes a four-byte signed integer to the current stream and
advances the stream position by four bytes.
(Overrides BinaryWriterWrite(Int32).) |
| Write(Int64) |
Writes a eight-byte signed integer to the current stream and
advances the stream position by eight bytes.
(Overrides BinaryWriterWrite(Int64).) |
| Write(Single) |
Converts a Single value to its bits and writes an Int32 instance
which stores the bits.
(Overrides BinaryWriterWrite(Single).) |
| Write(String) |
Writes string to the stream prefixed by its length in "packed"
format.
(Overrides BinaryWriterWrite(String).) |
| Write(UInt16) |
Writes a two-byte unsigned integer to the current stream and
advances the stream position by two bytes.
(Overrides BinaryWriterWrite(UInt16).) |
| Write(UInt32) |
Writes a four-byte unsigned integer to the current stream and
advances the stream position by four bytes.
(Overrides BinaryWriterWrite(UInt32).) |
| Write(UInt64) |
Writes a eight-byte unsigned integer to the current stream and
advances the stream position by eight bytes.
(Overrides BinaryWriterWrite(UInt64).) |
| Write(Byte, Int32, Int32) | (Inherited from BinaryWriter.) |
| Write(Char, Int32, Int32) | (Inherited from BinaryWriter.) |
| Write7BitEncodedInt | (Inherited from BinaryWriter.) |
| WritePackedInt32 |
Write an Int32 value using a variable-length storage
format.
|
| WritePackedInt64 |
Write an Int64 value using a variable-length storage
format.
|
| WritePackedRawInt128 |
Write a RawInt128 value to DataWriter.
|
Fields| Name | Description | |
|---|---|---|
 | OutStream | (Inherited from BinaryWriter.) |
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.
