C#的dll已经用Regasm指令注册过了
现在情况是 dll必须和exe在同一个目录下, 才可以正常调用
不在同一目录下 就提示找不到文件
调用dll的代码如下: var
aClass: Variant;
begin
CoInitialize(nil); ;
aClass:= CreateOleObject('NewProject.Test');
aClass.ShowForm;
aClass:=Unassigned;
CoUnInitialize;
end;
有哪位高人知道 麻烦指点一下 谢谢~

那注册时应该把DLL路径写到注册表中了啊,找找是不是正确的路径
按照自动化COM对象的用法,即使是用脚本也能调用这个对象,而不管你DLL与vbs文件是不是放一起.可以重新建个对象,写一个最简单的方法,show个messagebox测试一下
Example:
Code:
// IAddInterface.cs
public interface IAddInterface
{
int Add(int i1, int i2);
}Code:
// SimpleDll.cs
using System.Runtime.InteropServices;[ClassInterface(ClassInterfaceType.None)]
public class SimpleDLL : IAddInterface
{
public int Add(int i1, int i2)
{
return i1+i2;
}
}Compile using:
Code:
csc /t:library /out:SimpleDll.dll *.cs
Next, register the assembly as a COM object in the registry using:
Code:
regasm SimpleDll.dll /tlb:Add.tlb
(The above command will also generate a type library for use in Delphi.)Now you can switch over to Delphi, and click Project->Import Type Library (like you did before). Select your .tlb (Add.tlb in this case) and click Create Unit.In your main unit add "ComObj" and "SimpleDLL_TLB" (or whatever your generated unit is called) to your uses list and write the code to call your .NET methods. Example:
Code:
procedure TForm1.Button1Click(Sender: TObject);
var
intfRef: IAddInterface;
result: Integer;
begin
intfRef := CreateComObject(CLASS_SimpleDLL_) as IAddInterface;
result := intfRef.Add(2, 2);
.
.
For it to work your Delphi .exe needs to be in the same directory as the .NET DLL.

国外论坛上找的 最后一句话 太打击人了 ~~~~~~ 郁闷
copy那几个dll过来吧~
