DllNotFoundException 类

定义

当未找到在 DLL 导入中指定的 DLL 时所引发的异常。The exception that is thrown when a DLL specified in a DLL import cannot be found.

public ref class DllNotFoundException : TypeLoadException
[System.Runtime.InteropServices.ComVisible(true)]

注解

DllNotFoundException使用 COR_E_DLLNOTFOUND 值为0x80131524 的 HRESULT。DllNotFoundException uses the HRESULT COR_E_DLLNOTFOUND, which has the value 0x80131524.

有关实例的初始属性值的列表DllNotFoundException,请参阅DllNotFoundException构造函数。For a list of initial property values for an instance of DllNotFoundException, see the DllNotFoundException constructors.

当找不到System.Runtime.InteropServices.DllImportAttribute由特性定义的动态链接库或可比较的语言构造 (如 Visual Basic Declare语句) 时, 将引发。 DllNotFoundExceptionThe DllNotFoundException is thrown when a dynamic link library defined by the System.Runtime.InteropServices.DllImportAttribute attribute or a comparable language construct, such as the Visual Basic Declare statement, cannot be found. 当公共语言运行时无法加载 .NET Framework 程序集时, 不会引发此异常。It is not thrown when the common language runtime is unable to load a .NET Framework assembly.

请注意, DllImportAttribute可以指定 DLL 所在的目录的路径。Note that the DllImportAttribute can specify the path to the directory in which the DLL resides. 如果未指定路径, 则 Windows 将使用动态链接库搜索顺序中所述的搜索顺序。If a path is not specified, Windows uses the search order described in Dynamic-Link Library Search Order.
