Non méthode statique nécessite une cible C#

J'ai un win formulaire d'application avec une zone de liste afficher méthodes (par attribut). Je cherche à invoquer dynamiquement des méthodes dans un fil de discussion, en utilisant la réflexion de méthode d'obtenir des informations à partir de la valeur sélectionnée de la zone de liste. Cependant, lors de l'appel de Methodinfo.Invoquer je reçois cette exception interne "Non-statique méthode nécessite une cible C#".

Voici mon code (gardez à l'esprit que je suis encore novice en c# et la programmation en général.)

private void PopulateComboBox()
{//Populates list box by getting methods with declared attributes
MethodInfo[] methods = typeof(MainForm).GetMethods();
MyToken token = null;
List<KeyValuePair<String, MethodInfo>> items =
new List<KeyValuePair<string, MethodInfo>>();
foreach (MethodInfo method in methods)
{
token = Attribute.GetCustomAttribute(method,
typeof(MyToken), false) as MyToken;
if (token == null)
continue;
items.Add(new KeyValuePair<String, MethodInfo>(
token.DisplayName, method));
}
testListBox.DataSource = items;
testListBox.DisplayMember = "Key";
testListBox.ValueMember = "Value";
}
public void GetTest()
{//The next two methods handle selected value of the listbox and invoke the method.
if (testListBox.InvokeRequired)
testListBox.BeginInvoke(new DelegateForTest(functionForTestListBox));
else
functionForTestListBox();
}
public void functionForTestListBox()
{
_t = testListBox.SelectedIndex;
if (_t < 0)
return;
_v = testListBox.SelectedValue;
method = _v as MethodInfo;
if (method == null)
return;
_selectedMethod = method.Name;
MessageBox.Show(_selectedMethod.ToString());
method.Invoke(null, null);//<----Not sure about this. it runs fine when I dont invoke in a thread.
counter++;
}
private void runTestButton_Click(object sender, EventArgs e)
{//Click event that calls the selected method in the thread
if (_serverStatus == "Running")
{
if (_testStatus == "Not Running")
{
//create Instance new Thread and add function
//which will do some work
try
{
SetupTestEnv();
//functionForOutputTextBox();
Thread UIthread = new Thread(new ThreadStart(GetTest));
UIthread.Name = "UIThread";
UIthread.Start();
//Update test status
_testStatus = "Running";
//Make thread global
_UIthread = UIthread;
}
catch
{
MessageBox.Show("There was an error at during the test setup(Note: You must install each web browser on your local machine before attempting to test on them).");
}
}
else
{
MessageBox.Show("Please stop the current test before attempt to start a new one");
}
}
else
{
MessageBox.Show("Please make sure the server is running");
}
}
