示例1: Validate
public static bool Validate(Control.ControlCollection controls, Func<Exception, Control, bool> onError = null)
{
bool result = true;
Control currentControl = null;
try
{
foreach (Control control in controls.Cast<Control>().OrderBy(o => o.TabIndex))
{
currentControl = control;
//-------------------------------------------------------------------------
// Verificar se o controle implementa a interface IValidate
//-------------------------------------------------------------------------
IValidate validate = control as IValidate;
if (validate == null)
{
//não implementa, procurar o método validate
MethodInfo mi = control.GetType().GetMethods().FirstOrDefault(w =>
w.Name == "Validate" &&
w.GetParameters().Count() == 0);
if (mi != null)
{
if (mi.ReturnType == typeof(void) || mi.ReturnType != typeof(bool))
mi.Invoke(control, null);
else
result = Unimake.Convert.ToBoolean(mi.Invoke(control, null));
}
}
else//como implementa, então validar pela interface
result = validate.Validate();
if (!result) break;
if (control.Controls.Count > 0)
result = Validate(control.Controls);
if (!result) break;
}
}
catch (Exception ex)
{
if (onError != null)
return onError(ex, currentControl);
throw;
}
return result;

/// <summary>
/// Find the label by key and return a label control
/// </summary>
/// <param name="controlKey">control name</param>
/// <param name="controls">list of controls</param>
/// <returns></returns>
public static Control FindControlByKey(string controlKey, Control.ControlCollection controls)
{
Control ctrl = controls.Cast<Control>().Where(a => a.Name.ToLower().Contains(controlKey.ToLower())).FirstOrDefault();
return ctrl;
