IDataRecord.GetChars Method (Int32, Int64, Char, Int32, Int32)
Reads a stream of characters from the specified column offset into the buffer as an array, starting at the given buffer offset.
Assembly: System.Data (in System.Data.dll)
long GetChars( int i, long fieldoffset, char buffer, int bufferoffset, int length )
The zero-based column ordinal.
The index within the row from which to start the read operation.
The buffer into which to read the stream of bytes.
The index for buffer to start the read operation.
The number of bytes to read.
Return ValueType: System.Int64
The actual number of characters read.
returns the number of available characters in the field. Frequently this is the exact length of the field. However, the number returned may be less than the exact length of the field if GetChars has already been used to obtain characters from the field.
If you pass a buffer that is null, GetChars returns the length of the field in characters.
No conversions are performed; therefore the data retrieved must already be a character array.
