C#反射调用程序集中的方法

将dll注入进行到进程之后获取程序集信息及反射调用方法，记录一下备忘。

获取程序集集合，找出需要用的那个
Assembly[] assemblies = AppDomain.CurrentDomain.GetAssemblies();
Assembly assembly = assemblies.Where(p => p.FullName.Contains("XXXXX")).FirstOrDefault();
Type[] types = assembly.GetTypes();

//调用XXXXX.ClassName中的MethodName方法
Type type = assembly.GetType("XXXXX.ClassName");
object obj = Activator.CreateInstance(type, BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public, null, null, null);
MethodInfo methodRunCom = type.GetMethod("MethodName", BindingFlags.NonPublic | BindingFlags.Instance);
object objResult = methodRunCom.Invoke(obj, null);
string ret2 = objResult == null ? string.Empty : objResult.ToString(); //把返回处理成自己需要的格式

//获取XXXXX.ClassName中的控件
Type type = assembly.GetType("XXXXX.ClassName");
MethodInfo[] infos = type.GetMethods(BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public);
object obj = Activator.CreateInstance(type, BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public, null, null, null);
//控件处理
System.Windows.Forms.TextBox textBox = (System.Windows.Forms.TextBox)type.GetField("TextBoxName", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj);
textBox.Text = "123456789";
System.Windows.Forms.RadioButton radioButton = (System.Windows.Forms.RadioButton)type.GetField("RadioButtonName", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj);
radioButton.Checked = false;
//调用click
MethodInfo btnOKMethodInfo = type.GetMethod("btnXXX_Click", BindingFlags.Instance | BindingFlags.NonPublic);
object[] param = new object[] { new object(), new EventArgs() };
object objResult = btnOKMethodInfo.Invoke(obj, param);

//获取属性值
Type type = assembly.GetType("XXX.ClassName");
MethodInfo methodInfo = type.GetMethod("CreateInstance");
object obj = methodInfo.Invoke(null, null);
string propertyName = "PropertyName";
IEnumerable<PropertyInfo> property = from pi in obj.GetType().GetProperties() where pi.Name.ToLower() == propertyName.ToLower() select pi;
object propertyValueObj = property.First().GetValue(obj, null);
string value = propertyValueObj.ToString();
