Switch statement dont work with variables

string strCursor = i18n.Get("config.detectionMethod.cursor");
string strPlayer = i18n.Get("config.detectionMethod.player");

switch (Config.DetectionMethod)
{
    case strCursor:
        CheckTile(currentLocation, cursorTile, player);
        break;
    case strPlayer:
        CheckTile(currentLocation, toolLocation, player);
        break;
}

string strCursor = i18n.Get("config.detectionMethod.cursor");
string strPlayer = i18n.Get("config.detectionMethod.player");

switch (Config.DetectionMethod)
{
    case strCursor:
        CheckTile(currentLocation, cursorTile, player);
        break;
    case strPlayer:
        CheckTile(currentLocation, toolLocation, player);
        break;
}
