C# C语言中CreateObject的等价代码#
我有一个VB6的代码。有谁能告诉我如何用C# C语言中CreateObject的等价代码#,c#,com,C#,Com,我有一个VB6的代码。有谁能告诉我如何用C.写吗。该代码如下: Set Amibroker = CreateObject("Broker.Application") Set STOCK = Amibroker.Stocks.Add(ticker) Set quote = STOCK.Quotations.Add(stInDate) quote.Open = stInOpen quote.High = stInHigh quote.Low = stInlow quote.Close = stIn
C.
写吗。该代码如下:
Set Amibroker = CreateObject("Broker.Application")
Set STOCK = Amibroker.Stocks.Add(ticker)
Set quote = STOCK.Quotations.Add(stInDate)
quote.Open = stInOpen
quote.High = stInHigh
quote.Low = stInlow
quote.Close = stInYcp
quote.Volume = stInVolume
Set STOCK = Nothing
Set quote = Nothing
C#中的
CreateObject
等价物是什么?。我尝试添加对com对象的引用,但找不到任何Broker.Application或amibroker之类的com对象。如果您使用的是.net 4或更高版本,因此可以使用动态
,您可以非常简单地执行此操作。下面是一个使用Excel自动化界面的示例
Type ExcelType = Type.GetTypeFromProgID("Excel.Application");
dynamic ExcelInst = Activator.CreateInstance(ExcelType);
ExcelInst.Visible = true;
如果你不能使用动态,那么它会更混乱
Type ExcelType = Type.GetTypeFromProgID("Excel.Application");
object ExcelInst = Activator.CreateInstance(ExcelType);
ExcelType.InvokeMember("Visible", BindingFlags.SetProperty, null,
ExcelInst, new object[1] {true});
试着这么做会榨干你的命脉
如果您可以使用早期绑定分派,而不是如上所示的后期绑定分派,那么COM就容易多了。是否确实找不到COM对象的正确引用?如果使用.NET Framework 4.0及更高版本,则可以使用以下模式:
public sealed class Application: MarshalByRefObject {
private readonly dynamic _application;
// Methods
public Application() {
const string progId = "Broker.Application";
_application = Activator.CreateInstance(Type.GetTypeFromProgID(progId));
}
public Application(dynamic application) {
_application = application;
}
public int Import(ImportType type, string path) {
return _application.Import((short) type, path);
}
public int Import(ImportType type, string path, string defFileName) {
return _application.Import((short) type, path, defFileName);
}
public bool LoadDatabase(string path) {
return _application.LoadDatabase(path);
}
public bool LoadLayout(string path) {
return _application.LoadLayout(path);
}
public int Log(ImportLog action) {
return _application.Log((short) action);
}
public void Quit() {
_application.Quit();
}
public void RefreshAll() {
_application.RefreshAll();
}
public void SaveDatabase() {
_application.SaveDatabase();
}
public bool SaveLayout(string path) {
return _application.SaveLayout(path);
}
// Properties
public Document ActiveDocument {
get {
var document = _application.ActiveDocument;
return document != null ? new Document(document) : null;
}
}
public Window ActiveWindow {
get {
var window = _application.ActiveWindow;
return window != null ? new Window(window) : null;
}
}
public AnalysisDocs AnalysisDocs {
get {
var analysisDocs = _application.AnalysisDocs;
return analysisDocs != null ? new AnalysisDocs(analysisDocs) : null;
}
}
public Commentary Commentary {
get {
var commentary = _application.Commentary;
return commentary != null ? new Commentary(commentary) : null;
}
}
public Documents Documents {
get {
var documents = _application.Documents;
return documents != null ? new Documents(documents) : null;
}
}
public string DatabasePath {
get { return _application.DatabasePath; }
}
public bool Visible {
get { return _application.Visible != 0; }
set { _application.Visible = value ? 1 : 0; }
}
public string Version {
get { return _application.Version; }
}
}
}
接下来,您必须包装所有的OLE自动化类。例如,总结评论类:
public sealed class Commentary : MarshalByRefObject {
// Fields
private readonly dynamic _commentary;
// Methods
internal Commentary(dynamic commentary) {
_commentary = commentary;
}
public void Apply() {
_commentary.Apply();
}
public void Close() {
_commentary.Close();
}
public bool LoadFormula(string path) {
return _commentary.LoadFormula(path);
}
public bool Save(string path) {
return _commentary.Save(path);
}
public bool SaveFormula(string path) {
return _commentary.SaveFormula(path);
}
}
下面是我用来自动化Amibroker的C代码的一个片段(从我走上这条道路时开始)。您需要参考System.Runtime.Interopservices
System.Type objType = System.Type.GetTypeFromProgID("Broker.Application");
dynamic comObject = System.Activator.CreateInstance(objType);
comObject.Import(0, fileName, "default.format");
comObject.RefreshAll();
不过,键入一个点不会显示comObject内部方法
关于这个方法,我能说的就是——它很有效,就像一个符咒,但要远离它,就像大卫说的那样。我对这种方法的灵感来自:
对于另一个攻击角度,您可能希望查看(我认为这是早期绑定):
希望这些至少能对你有所帮助。我在Amibroker和C#中使用了这两种方法,但最终我将它们抛在了后面。COM和Amibroker不太合拍。就连TJ也这么说
祝你好运。诸如此类的事情。如果您使用的是.NET4.0,则可以使用dynamic来访问it成员。对于那些像我一样对此有编译问题的人,请确保参考Microsoft.Csharp和System.Core。这是否适用于32位和64位Excel?或者.Net实例需要匹配Excel位吗?@Turn Excel已用完进程,因此您不需要任何位匹配
