Syntax
'Declaration
 
Public Function GetChars( _
   ByVal dataIndex As Long, _
   ByVal buffer() As Char, _
   ByVal bufferIndex As Integer, _
   ByVal length As Integer _
) As Long
 

Parameters

dataIndex
The specified column offset.
buffer
The specified buffer to read data to.
bufferIndex
The specified buffer offset.
length
The number of characters to read.

Return Value

The actual number of characters read.
Remarks

If the buffer parameter is null, GetChars returns the length of the field in characters.

If the CacheData property is false, applications can only retrieve the complete set of data from a DB2Clob instance once (by any of the ways): via the GetChars method, Value property, or the ToString method. Tying to retrieve the current instance data again by any of the means results in System.InvalidOperationException.
