In this blog I will show you how to explore a given type properties, methods, fields and so forth programmatically. To do so, create a new windows application then add a label, a textbox, a button and a list box into it so that it appears like below:
![]()
Figure 1
Then add this code within the button1 event handler scope:
private void button1_Click(object sender, EventArgs e)
{
try
{
Person myPerson = new Person("Bejaoui", "Bechir");
Type myType = Type.GetType(textBox1.Text);
MemberInfo[] r = myType.GetMembers();
MessageBox.Show("The total number of members is : " + r.Length);
int index = 1;
foreach (MemberInfo x in r)
{
listBox1.Items.Add("Member" + index.ToString() + " : " + x.Name + " is " + x.MemberType);
index++;
}
}
catch (NullReferenceException caught)
{ MessageBox.Show("This is not a type",caught.Message); }
}
}
Run the application and put a given type within the textbox, say, System.DateTime for example, by the way a full name type is required to achieve the goal, otherwise, a null reference exception will be risen. Now, try to observe what happens.
Good Dotneting!!!
