如何使用.NET P / Invoke CryptUIWizExport函数
任何人都可以将这两个cryptui.dll函数/结构翻译成C＃.NET [dllimport]包装器吗？ 我想P / Invoke CryptUIWizExport函数来显示Windows证书导出向导。 特别是，我需要将.NET X509Certificate作为参数传递给CryptUIWizExport函数。 非常感谢你的帮助！
CryptUIWizExport函数
BOOL WINAPI CryptUIWizExport( __in DWORD dwFlags, __in HWND hwndParent, __in LPCWSTR pwszWizardTitle, __in PCCRYPTUI_WIZ_EXPORT_INFO pExportInfo, __in void *pvoid ); typedef struct _CRYPTUI_WIZ_EXPORT_INFO { DWORD dwSize; LPCWSTR pwszExportFileName; DWORD dwSubjectChoice; union { PCCERT_CONTEXT pCertContext; PCCTL_CONTEXT pCTLContext; PCCRL_CONTEXT pCRLContext; HCERTSTORE hCertStore; } ; DWORD cStores; HCERTSTORE *rghStores; } CRYPTUI_WIZ_EXPORT_INFO, *PCRYPTUI_WIZ_EXPORT_INFO; 您可以在不同情况下使用CryptUIWizExport函数。 以下是导出证书的示例。 可以轻松修改此示例，以便将其用于您需要它的情况。

尝试使用PInvoke Interop助手 。 您可以将其指向头文件，它将为您生成p / invoke签名。
