Question

Fairly new to wpf, using the galasoft mvvm templates.
I have two relaycommands that do the same thing, but they need to set different properties.

Can I do something like this?

public RelayCommand OpenDestinationCommand { get; private set; }
public RelayCommand OpenSourceCommand { get; private set; }

public MainViewModel(IDataService dataService)
{
    OpenSourceCommand = new RelayCommand(() => GetPath(SourcePathPropertyName));
    OpenDestinationCommand = new RelayCommand(() => GetPath(DestinationPathPropertyName));
}

private void GetPath(string PropertyName) {
    //show a dialog, get the path they select
    string newPath = GetPathFromDialog();
    //what should this look like? Is this possible?
    var Property = GetPropertyByName(PropertyName);
    Property.Set(newPath);
}

Shoulda googled first.

private PropertyInfo GetPropertyByName(string propName)
{
  return this.GetType().GetProperty(propName);
}

private void GetPath(string PropertyName) {
    //show a dialog, get the path they select
    string newPath = GetPathFromDialog();
    //what should this look like? Is this possible?
    var mProp = GetPropertyByName(PropertyName);
    mPropp.SetValue(this, newPath, null);
}
