是否VB和C#在这样的情况下,运行时候有差异呢?

VB
Public Sub New(ByVal context As DisplayContext)
MyBase.New(context, New NewUserAccountWizardManager(context.CallContext)) InitializeComponent()
End Sub

c#
public FormNewUserAccount(DisplayContext context)
: base(context, new NewUserAccountWizardManager(context.CallContext)) {
InitializeComponent();
}

在vb版本下,没有问,在C#版本下就出上面的错误.

参考下下面的代码？
特别是下面的这一行：propParent.SetValue(m_customcomponent, host.RootComponent);

IComponent m_customcomponent;
PropertyDescriptorCollection props;
PropertyDescriptor propParent;

foreach (DictionaryEntry m_icomponent in m_qdictionary)

{

string m_assemblyname = m_icomponent.Value.GetType().Name;

switch (m_assemblyname)

{

case "QLabel":

QLabel m_qlabelcomponent = (QLabel)m_icomponent.Value;

m_customcomponent = host.CreateComponent(typeof(QLabel));

//Find the properties for the label control

props = TypeDescriptor.GetProperties(m_qlabelcomponent);

//We assign the properties from serialized object to the new component.

((QLabel)m_customcomponent).Texto = (string)props["Texto"].GetValue(m_qlabelcomponent);

((QLabel)m_customcomponent).Nombre = (string)props["Nombre"].GetValue(m_qlabelcomponent);

// other properties

//Get the Parent property

propParent = props["Parent"];

//Set the Parent property to the form:

propParent.SetValue(m_customcomponent, host.RootComponent);

break;

case "QImage":

break;

//another members and code ommited...

}

}
