매개 변수

• i
  The zero-based ordinal position of the column to be retrieved.

• fieldOffset
  The zero-based index within the column from which to begin reading data.

• buffer
  The buffer into which to read the stream of characters.

• bufferoffset
  The zero-based index within the buffer from which to begin writing data.

• length
  The number of characters to read from the column.

반환 값

A Long that contains the number of characters actually read from the column.

주의

The GetChars method returns the number of available characters in the field. In most cases this is the exact length of the field. However, the number returned may be less than the true length of the field if GetChars has already been used to obtain characters from the field.

If you pass a null reference (Nothing in Microsoft Visual Basic) in the buffer parameter, GetBytes returns the length of the column in characters.

No conversions are performed; therefore the data retrieved must already be a character array.
