如何将事件的用法从C#转换为VB.net [英] How to convert usage of an event from C# to VB.net
问题描述
我正在尝试将Alvaro Mendez的旧文章"RW XML文件，配置文件，INI文件或注册表"从C#转换为vb.net.我使用了一个非常好的程序"InstantVB"进行转换，但是它偶然发现了所有代码中的一项.它与转换两个事件的使用有关.一般而言，我对使用事件不是很有经验，也不知道从哪里开始尝试解决此问题.任何帮助，将不胜感激.我已经包含了原始C#中的相关代码和Converter中的VB.net代码.
任何帮助将不胜感激.

有问题的C#代码如下(我在结尾处的两个罪魁祸首处用星号标记:
################################################ #############
I am trying to convert "RW XML Files, Config Files, INI files, or the Registry", an old article by Alvaro Mendez, from C# to vb.net. I use a very good program named "InstantVB" for the conversion, but it stumbled on one item out of all the code. It has to do with converting the use of two events. I am not very experienced with using events in general, and don''t know where to start in trying to fix this. Any help would be appreciated. I have included the relevant code from the original C# and the VB.net code from the Converter.
Any help would be very much appreciated.

The C# code in question is as follows (I marked the two culprit lines at the end with an asterisk:
##############################################################
namespace AMS.Profile
{
/// <summary>
/// Abstract base class for all Profile classes in this namespace.
/// </summary>
/// <remarks>
/// This class contains fields and methods which are common for all the
/// derived Profile classes.
/// It fully implements most of the methods and properties of its base
/// interfaces so that
/// derived classes don't have to. </remarks>
public abstract class Profile : IProfile
{
// Fields
private string m_name;
private bool m_readOnly;
/// <summary>
/// Event used to notify that the profile is about to be changed.
/// <summary>
/// <seealso cref="Changed" />
public event ProfileChangingHandler Changing;
/// <summary>
/// Event used to notify that the profile has been changed.
/// </summary>
/// <seealso cref="Changing" />
public event ProfileChangedHandler Changed;
/// <summary>
/// Initializes a new instance of the Profile class by setting the
/// <see cref="Name" /> to <see cref="DefaultName" />. </summary>
protected Profile()
{
m_name = DefaultName;
}
/// <summary>
/// Initializes a new instance of the Profile class by setting the
/// <see cref="Name" /> to a value. </summary>
/// <param name="name">
/// The name to initialize the <see cref="Name" /> property with. </param>
protected Profile(string name)
{
m_name = name;
}
/// <summary>
/// Initializes a new instance of the Profile class based on another Profile object. </summary>
/// <param name="profile">
/// The Profile object whose properties and events are used to initialize the object being constructed. </param>
protected Profile(Profile profile)
{
m_name = profile.m_name;
m_readOnly = profile.m_readOnly;
* Changing = profile.Changing;
* Changed = profile.Changed;
}
################################################ #############
它将转换为VB.net为(再次使用星号):
################################################ #############
##############################################################
It translates to VB.net as (again I use an asterisk):
##############################################################

m_name = profile.m_name
m_readOnly = profile.m_readOnly
* AddHandler Changing, profile.Changing
* AddHandler Changed, profile.Changed
End Sub ########################################### ##################
VB.net关于这些行的投诉如下:
##############################################################
VB.net''s complaint about the lines are as follows:
'Public Event Changing(sender As Object, e As ProfileChangingArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
'Public Event Changed(sender As Object, e As ProfileChangedArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
你能告诉我在VB.net中应该如何处理吗?
谢谢.
Can you possibly tell me how this should be handled in VB.net.
Thank you.
