Paramètres

  • ordinal
    Type : System. . :: . .Int32
    An Int32 value that specifies the column position at which to retrieve the character array value.
  • fieldoffset
    Type : System. . :: . .Int64
    An Int32 value that specifies the index position within the record from which to begin the read operation.
  • buffer
    Type : array<System. . :: . .Char> [] () [] []
    A Uint8 array that specifies the buffer into which to read the character array.

Valeur de retour

Type : System. . :: . .Int64
An Int64 value that specifies the number of characters returned in the array.
