在ASP.NET Core中,可以通过以下方式与旧版本的框架进行交互:
示例代码:
// 旧版本框架的代码
public class LegacyClass
{
public string GetData()
{
return "Data from legacy class";
}
}
// .NET Standard库的代码
public class LegacyInterop
{
private LegacyClass _legacyClass;
public LegacyInterop()
{
_legacyClass = new LegacyClass();
}
public string GetDataFromLegacyClass()
{
return _legacyClass.GetData();
}
}
// ASP.NET Core的代码
public class HomeController : Controller
{
private LegacyInterop _legacyInterop;
public HomeController()
{
_legacyInterop = new LegacyInterop();
}
public IActionResult Index()
{
string data = _legacyInterop.GetDataFromLegacyClass();
return View(data);
}
}
示例代码:
public class HomeController : Controller
{
[DllImport("legacy.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int GetDataFromLegacyComponent(StringBuilder buffer, int bufferSize);
public IActionResult Index()
{
StringBuilder buffer = new StringBuilder(255);
int dataSize = GetDataFromLegacyComponent(buffer, buffer.Capacity);
string data = buffer.ToString(0, dataSize);
return View(data);
}
}
请注意,这仅是两种可能的解决方法之一,具体方法取决于旧版本框架的特定要求和限制。
