|Method|Description|
29-
|------------|-----------------|
30-
|[IDiaEnumSourceFiles::get__NewEnum](../../debugger/debug-interface-access/idiaenumsourcefiles-get-newenum.md)|Retrieves the `IEnumVARIANT Interface` version of this enumerator.|
31-
|[IDiaEnumSourceFiles::get_Count](../../debugger/debug-interface-access/idiaenumsourcefiles-get-count.md)|Retrieves the number of source files.|
32-
|[IDiaEnumSourceFiles::Item](../../debugger/debug-interface-access/idiaenumsourcefiles-item.md)|Retrieves a source file by means of an index.|
33-
|[IDiaEnumSourceFiles::Next](../../debugger/debug-interface-access/idiaenumsourcefiles-next.md)|Retrieves a specified number of source files in the enumeration sequence.|
34-
|[IDiaEnumSourceFiles::Skip](../../debugger/debug-interface-access/idiaenumsourcefiles-skip.md)|Skips a specified number of source files in an enumeration sequence.|
35-
|[IDiaEnumSourceFiles::Reset](../../debugger/debug-interface-access/idiaenumsourcefiles-reset.md)|Resets an enumeration sequence to the beginning.|
36-
|[IDiaEnumSourceFiles::Clone](../../debugger/debug-interface-access/idiaenumsourcefiles-clone.md)|Creates an enumerator that contains the same enumeration state as the current enumerator.|

## Notes for Callers
41-
Obtain this interface by calling the `QueryInterface` method on an [IDiaTable](../../debugger/debug-interface-access/idiatable.md) object. See the example for details.
42-
43-
## Example
44-
This example shows how to obtain the `IDiaEnumSourceFiles` interface from the list of tables in a DIA session object. For an example of accessing source file information, see the [IDiaSourceFile](../../debugger/debug-interface-access/idiasourcefile.md) interface.
