示例1: SqlRandomTable

{
if (columns == null || columns.Length == 0)
throw new ArgumentException("non-empty type array is required");

if (primaryKeyColumnIndex.HasValue && (primaryKeyColumnIndex.Value < 0 || primaryKeyColumnIndex.Value >= columns.Length))
throw new ArgumentOutOfRangeException("primaryColumnIndex");
PrimaryKeyColumnIndex = primaryKeyColumnIndex;
_columns = (SqlRandomTableColumn[])columns.Clone();

else

else
