 | CheckIfEmpty | |
| Clear | Overloaded. Removes all elements from the SparseArray at the specified range. |
| Clone | Creates a new object that is a copy of the current instance. |
| Contains | Determines whether the SparseArray contains a specific value. |
 | Copy | Copies a range of elements from an SparseArray starting at the specified source index and pastes them to another SparseArray starting at the specified target index. The length and the indexes are specified as 32-bit integers. |
| CopyTo | Overloaded. Copies all the elements of the current one-dimensional System.Array to the specified one-dimensional SparseArray starting at the specified destination SparseArray index. The index is specified as a 32-bit integer. |
| Equals | Overloaded. Indicates whether the current object is equal to another object of the same type. |
| Fill | Fills a range of array with a specified value. |
| IndexOf | Determines the index of a specific item in the SparseArray. |
| InsertRange | Inserts the specified number of new null items into the SparseArray at the specified index. |
| Move | Moves a range of elements from an SparseArray starting at the specified source index and pastes them to another SparseArray starting at the specified target index. Elements of old range will be clear. The length and the indexes are specified as 32-bit integers. |
| NextNonEmptyIndex | Overloaded. |
| NextNonEmptyQuickAccessKey | |
| PreviousNonEmptyIndex | Overloaded. |
| RemoveRange | Removes a range of items from the SparseArray. |
| Swap | Swaps a range of elements from an SparseArray starting at the specified source index with another SparseArray starting at the specified target index. The length and the indexes are specified as 32-bit integers. |
