C1.C1DataExtender.2 Assembly / C1.C1DataExtender Namespace / C1DataView Class / Find Method / Find(String[],Object[]) Method
An array of column names to search on.
An array of values of the columns specified in the columnNames parameter. The length and order of values must correspond to column names specified in the columnNames parameter. If the System.Type of some array value differs from the C1ViewColumn.DataType of the corresponding column then this value will be converted to the column's target type automatically. In the case where such a conversion is impossible, an exception will be raised.
