在调用时有两件事对我们不利getStLinkList特别是“CubeProgrammer_API.dll”库的功能。如果不更正它们，库将无法工作，即使是在 C++ 中也是如此。
首先，在中找到该库的依赖项api/libSTM32CubeProgrammer 安装的文件夹并非全部针对 x64 编译。中的版本bin文件夹是，这些是您希望在运行时可用的库。我通过将工作目录设置为项目调试设置中的该目录来完成此操作。这是通过检查每个 DLL 的目标机器来验证的api/lib and bin文件夹。
二、调用前需要初始化“CubeProgrammer_API.dll”getStLinkList通过致电setLoadersPath and setDisplayCallbacks功能。第一个函数必须提供“Flash Loader”的路径，即bin/FlashLoader就我而言。这setDisplayCallbacksfunction 采用三个函数指针的结构。
下面的示例可能不是类型封送的最佳示例，但它将说明该过程。

}

}
public static IList<DebugConnectParameters> GetStLinkProgrammers(bool shared = false)
{
var listPtr = Marshal.AllocHGlobal(Marshal.SizeOf<IntPtr>());
var parametersList = new List<DebugConnectParameters>();
try
{
var size = Marshal.SizeOf<DebugConnectParameters>();
var numberOfItems = NativeMethods.GetStLinkList(listPtr, shared ? 1U : 0U);
var listDereference = Marshal.PtrToStructure<IntPtr>(listPtr);
for (var i = 0; i < numberOfItems; i++)
{
var currentItem = Marshal.PtrToStructure<DebugConnectParameters>(listDereference + (i * size));
parametersList.Add(currentItem);
}
NativeMethods.deleteInterfaceList();
}
finally
{
Marshal.FreeHGlobal(listPtr);
}
return parametersList;
}
public static void FreeStLinkProgrammers()
{
NativeMethods.deleteInterfaceList();
}
}
以及主要：
class Program
{
static void Main(string[] args)
{
CubeProgrammerApi.SetLoadersPath(@"C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\FlashLoader");
CubeProgrammerApi.SetDisplayCallbacks(InitProgressBar, ReceiveMessage, ProgressBarUpdate);
var stLinkList = CubeProgrammerApi.GetStLinkProgrammers();
foreach (var stlink in stLinkList)
{
Console.WriteLine("{0} {1}", stlink.Index, stlink.SerialNumber);
}
Console.WriteLine("Press ENTER to exit");
Console.ReadLine();
CubeProgrammerApi.FreeStLinkProgrammers();
}
static void ReceiveMessage(int messgaeType, string message)
{
}
static void InitProgressBar()
{
}
static void ProgressBarUpdate(int currentProgress, int total)
{
}
}
这将输出以下内容，并附加两个调试器，分别是 STLink V3 和 STLink V2。这应该能让您足够了解要使用的正确类型。
