C How to get a sub build of a registry key

Just go through it. Use getsubkeynames and getvalues to get all the subkeys and value names, and then iterate over them, e.g. with recursion.

This class implements functions such as registry read, write, delete, and lookup.

Implementation**: using system;

using ;

using ;

using ;

using ;

namespace tagreceiver

return registdata;

Write data to the registry.

///////public void setregistrydata(registrykey root, string subkey, string name, string value)

Delete the registry key specified in the registry.

////public void deleteregist(registrykey root, string subkey, string name) }

Determines whether a specified registry key exists.

///////public bool isregistryexist(registrykey root, string subkey, string name) }

return _exit; }
