语法

声明
Public Function GetChars ( _
    i As Integer, _
    fieldoffset As Long, _
    buffer As Char(), _
    bufferoffset As Integer, _
    length As Integer _
) As Long
用法
Dim instance As DataProvider
Dim i As Integer
Dim fieldoffset As Long
Dim buffer As Char()
Dim bufferoffset As Integer
Dim length As Integer
Dim returnValue As Long

returnValue = instance.GetChars(i, fieldoffset, _
    buffer, bufferoffset, length)

public long GetChars(
    int i,
    long fieldoffset,
    char[] buffer,
    int bufferoffset,
    int length
)

public:
virtual long long GetChars(
    int i, 
    long long fieldoffset, 
    array<wchar_t>^ buffer, 
    int bufferoffset, 
    int length
) sealed

public final function GetChars(
    i : int, 
    fieldoffset : long, 
    buffer : char[], 
    bufferoffset : int, 
    length : int
) : long

参数

  • fieldoffset
    类型：System. . :: . .Int64
    The index within the field from which to begin the read operation.
  • buffer
    类型：array<System. . :: . .Char> [] () [] []
    The buffer into which to read the stream of bytes.
  • bufferoffset
    类型：System. . :: . .Int32
    The index within the buffer where the write operation is to start.

返回值

类型：System. . :: . .Int64
The number of characters read.

实现

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