Answer 1

string strMPageURL ="http://abcd.com/sites/forum/_catalogs/masterpage/MyCustomMasterPage.master";

SPFolder mPageFolder = spWeb.Folders["_catalogs"].SubFolders["masterpage"];
using (WebClient oWebClient = new WebClient())
{
    SPFileCollection mPageFileCollection = mPageFolder.Files;
    SPFile mPageFile = mPageFileCollection.Add(
        "MyCustomMasterPage.master",
        oWebClient.OpenRead(strMPageURL)
    );
}

It actually behaves like you are uploading the masterpage to the _catalogs/masterpage folder but the difference is that it came from the web not from the local machine.

If you plan to upload the masterpage just like how your out of the box behave using file upload from local machine, you can do this.

string strMPageLocation =@"C://MyCustomMasterPage.master";

SPFolder mPageFolder = spWeb.Folders["_catalogs"].SubFolders["masterpage"];
using (FileStream mPageStream = new FileStream(strMPageLocation,FileMode.Open))
{
    SPFileCollection mPageFileCollection = mPageFolder.Files;
    SPFile mPageFile = mPageFileCollection.Add(
        "MyCustomMasterPage.master",
        mPageStream
    );
}
