Populates an array of objects with the column values of the current row.
Assembly: System.Data (in System.Data.dll)
Return ValueType: System::Int32
The number of column values copied into the array.
For most applications, this method provides an efficient means for retrieving all columns, instead of retrieving each column individually. If your intent is to retrieve all the column values from a row within the DataTableReader, the GetValues method provides the most efficient solution.
You can pass an Object array that contains fewer than the number of columns that are contained in the resulting row. Only the amount of data the Object array can hold is copied to the array. You can also pass an Object array whose length is more than the number of columns that are contained in the resulting row, in which case the additional array elements remains unchanged by the method call.
This method places DBNull in the output array for null columns.
The following example demonstrates using an array that is the correct size, to read all values from the current row in the supplied DataTableReader. In addition, the sample demonstrates using a fixed-sized array that could be either smaller or larger than the number of available columns.
