Private void button2_Click (object sender, EventArgs e)
{

// Obtain the variable value through a string
MessageBox. Show (this. GetType (). GetField ("gisoracle"). GetValue (this). ToString ());
// Assign a value to the variable
This. GetType (). GetField ("gisoracle"). SetValue (this, "gisoracle@126.com ");
// New Value
MessageBox. Show (this. GetType (). GetField ("gisoracle"). GetValue (this). ToString ());
}
