声明
Public Function GetChars ( _
i As Integer, _
fieldoffset As Long, _
buffer As Char(), _
bufferoffset 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(

array<wchar_t>^ buffer,
int bufferoffset,
int length
) sealed
abstract GetChars :

参数
- i
类型:System.Int32
The zero-based column ordinal.
- 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.
- length
类型:System.Int32
The maximum length to copy into the buffer.
返回值
类型:System.Int64
The number of characters read.
实现
IDataRecord.GetChars(Int32, Int64, array<Char[], Int32, Int32)
