本文介绍了如何使用.NET的P / Invoke CryptUIWizExport功能的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
谁能翻译这两个cryptui.dll功能/结构成C＃.NET [dllimport的]包装？我想的P / Invoke的CryptUIWizExport函数来显示Windows证书导出向导。特别是，我需要通过一个.NET x509证书作为一个参数到CryptUIWizExport功能。你的帮助是多少AP preciated！
BOOL WINAPI CryptUIWizExport（
一切变得DWORD dwFlags中，
一切变得HWND hwndParent，
一切变得LPCWSTR pwszWizardTitle，
一切变得PCCRYPTUI_WIZ_EXPORT_INFO pExportInfo，
一切变得无效* PVOID
）;
typedef结构_CRYPTUI_WIZ_EXPORT_INFO {
DWORD的dwSize;
LPCWSTR pwszExportFileName;
DWORD dwSubjectChoice;
联盟 {
PCCERT_CONTEXT pCertContext;
PCCTL_CONTEXT pCTLContext;
PCCRL_CONTEXT pCRLContext;
HCERTSTORE hCertStore;
};
DWORD cStores;
HCERTSTORE * rghStores;
} CRYPTUI_WIZ_EXPORT_INFO，* PCRYPTUI_WIZ_EXPORT_INFO;
解决方案
您可以在不同的情况下使用 CryptUIWizExport 功能。这里有一个例子来导出证书。这个例子可以很容易修改为使用它在你需要它的情况。
使用系统;
使用了System.Runtime.InteropServices;
使用System.Security.Cryptography.X509Certificates;
命名空间CryptUIWizExportTest {
使用HCERTSTORE = IntPtr的;
使用HWND = IntPtr的;
静态内部类NativeMethods {
内部枚举CryptuiExportChoice：UINT {
CRYPTUI_WIZ_EXPORT_CERT_CONTEXT = 1，
CRYPTUI_WIZ_EXPORT_CTL_CONTEXT = 2，
CRYPTUI_WIZ_EXPORT_CRL_CONTEXT = 3，
CRYPTUI_WIZ_EXPORT_CERT_STORE = 4，
CRYPTUI_WIZ_EXPORT_CERT_STORE_CERTIFICATES_ONLY = 5，
CRYPTUI_WIZ_EXPORT_FORMAT_CRL = 6，
CRYPTUI_WIZ_EXPORT_FORMAT_CTL = 7
}
[StructLayout（LayoutKind.Sequential）

内部UINT的dwSize;
//要求：应设置为sizeof（CRYPTUI_WIZ_EXPORT_INFO）
内部字符串pwszExportFileName;
//必选如果CRYPTUI_WIZ_NO_UI标志设置，可选，否则。
//完全限定的文件名导出到，如果这是
//非NULL和CRYPTUI_WIZ_NO_UI标志没有设置，那么它是

内部CryptuiExportChoice dwSubjectChoice;
//要求：指明对象的类型：

// CRYPTUI_WIZ_EXPORT_CTL_CONTEXT
// CRYPTUI_WIZ_EXPORT_CRL_CONTEXT
// CRYPTUI_WIZ_EXPORT_CERT_STORE
// CRYPTUI_WIZ_EXPORT_CERT_STORE_CERTIFICATES_ONLY
内部IntPtr的pCertContext;

// PCCERT_CONTEXT pCertContext;

//可选：额外的门店数要搜索的的证书
//信任链如果链正在导出一个证书。
//这个被忽略，如果dwSubjectChoice是什么，其他

内部HCERTSTORE rghStores;
// HCERTSTORE * !!!!

exportInfo.dwSize =（UINT）Marshal.SizeOf（
typeof运算（NativeMethods.CRYPTUI_WIZ_EXPORT_INFO））;
//exportInfo.pwszExportFileName = @C：\ TEMP \ tt.cer;
exportInfo.dwSubjectChoice =
NativeMethods.CryptuiExportChoice.CRYPTUI_WIZ_EXPORT_CERT_CONTEXT;
exportInfo.pCertContext = x509.Handle;
exportInfo.cStores = 0;
IntPtr的pExportInfo = Marshal.AllocHGlobal（（INT）exportInfo.dwSize）;
Marshal.StructureToPtr（exportInfo，pExportInfo，假）;
NativeMethods.CryptUIWizExport（0，IntPtr.Zero，
pExportInfo，IntPtr.Zero导出证书）;
}
}
}
Can anyone translate these two cryptui.dll functions/structures into C#.NET [dllimport] wrappers? I would like to P/Invoke the CryptUIWizExport function to display the Windows Certificate Export Wizard. In particular, I need to pass a .NET X509Certificate as a parameter into the CryptUIWizExport function. You help is much appreciated!!!
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;
解决方案
You can use CryptUIWizExport function in different situations. Here is an example to export a certificate. This example can be easy modified for using it to the situations in which you need it.
using System;
using System.Runtime.InteropServices;
using System.Security.Cryptography.X509Certificates;
namespace CryptUIWizExportTest {
using HCERTSTORE = IntPtr;
using HWND = IntPtr;
static internal class NativeMethods {
internal enum CryptuiExportChoice : uint {
CRYPTUI_WIZ_EXPORT_CERT_CONTEXT = 1,
CRYPTUI_WIZ_EXPORT_CTL_CONTEXT = 2,
CRYPTUI_WIZ_EXPORT_CRL_CONTEXT = 3,
CRYPTUI_WIZ_EXPORT_CERT_STORE = 4,
CRYPTUI_WIZ_EXPORT_CERT_STORE_CERTIFICATES_ONLY = 5,
CRYPTUI_WIZ_EXPORT_FORMAT_CRL = 6,
CRYPTUI_WIZ_EXPORT_FORMAT_CTL = 7
}
[StructLayout (LayoutKind.Sequential)]
internal struct CRYPTUI_WIZ_EXPORT_INFO {
internal uint dwSize;
//Required: should be set to sizeof(CRYPTUI_WIZ_EXPORT_INFO)
internal string pwszExportFileName;
//Required if the CRYPTUI_WIZ_NO_UI flag is set, Optional otherwise.
//The fully qualified file name to export to, if this is
//non-NULL and the CRYPTUI_WIZ_NO_UI flag is NOT set, then it is
//displayed to the user as the default file name
internal CryptuiExportChoice dwSubjectChoice;
//Required: indicate the type of the subject:
// If can one of the following:
// CRYPTUI_WIZ_EXPORT_CERT_CONTEXT
// CRYPTUI_WIZ_EXPORT_CTL_CONTEXT
// CRYPTUI_WIZ_EXPORT_CRL_CONTEXT
// CRYPTUI_WIZ_EXPORT_CERT_STORE
// CRYPTUI_WIZ_EXPORT_CERT_STORE_CERTIFICATES_ONLY
internal IntPtr pCertContext;
//union
//{
// PCCERT_CONTEXT pCertContext;
// PCCTL_CONTEXT pCTLContext;
// PCCRL_CONTEXT pCRLContext;
// HCERTSTORE hCertStore;
//};
internal uint cStores;
// Optional: count of extra stores to search for the certs in the
// trust chain if the chain is being exported with a cert.
// this is ignored if dwSubjectChoice is anything other
// than CRYPTUI_WIZ_EXPORT_CERT_CONTEXT
internal HCERTSTORE rghStores;
// HCERTSTORE* !!!!
// Optional: array of extra stores to search for the certs in the
// trust chain if the chain is being exported with a cert.
// this is ignored if dwSubjectChoice is anything other
// than CRYPTUI_WIZ_EXPORT_CERT_CONTEXT
};

if (x509 == null)
return;
NativeMethods.CRYPTUI_WIZ_EXPORT_INFO exportInfo =
new NativeMethods.CRYPTUI_WIZ_EXPORT_INFO ();
exportInfo.dwSize = (uint)Marshal.SizeOf (
typeof (NativeMethods.CRYPTUI_WIZ_EXPORT_INFO));
//exportInfo.pwszExportFileName = @"C:\TEMP\tt.cer";
exportInfo.dwSubjectChoice =
NativeMethods.CryptuiExportChoice.CRYPTUI_WIZ_EXPORT_CERT_CONTEXT;
exportInfo.pCertContext = x509.Handle;
exportInfo.cStores = 0;
IntPtr pExportInfo = Marshal.AllocHGlobal ((int)exportInfo.dwSize);
Marshal.StructureToPtr (exportInfo, pExportInfo, false);
