參數

  • buffer
    型別：array<System. . :: . .Char> [] () [] []
    A Uint8 array that specifies the buffer into which to read the character array.

傳回值

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

實作

IDataRecord. . :: . .GetChars(Int32, Int64, array<Char> [] () [] [], Int32, Int32)
