我试图调用 DLL 文件，以便我可以使用dll中的函数 . 但我失败了 . 看到我遇到的错误：
#import "BPNN1.dll"
string Train(
double &inpTrain[], // Input training data (1D array carrying 2D data, old first)
double &outTarget[],// Output target data for training (2D data as 1D array, oldest 1st)
double &outTrain[], // Output 1D array to hold net outputs from training
int ntr, // # of training sets
int UEW, // Use Ext. Weights for initialization (1=use extInitWt, 0=use rnd)
double &extInitWt[],// Input 1D array to hold 3D array of external initial weights
double &trainedWt[],// Output 1D array to hold 3D array of trained weights
int numLayers, // # of layers including input, hidden and output
int &lSz[], // # of neurons in layers. lSz[0] is # of net inputs
int AFT, // Type of neuron activation function (0:sigm, 1:tanh, 2:x/(1+x))
int OAF, // 1 enables activation function for output layer; 0 disables
int nep, // Max # of training epochs
double maxMSE // Max MSE; training stops once maxMSE is reached
);
string Test(
double &inpTest[], // Input test data (2D data as 1D array, oldest first)
double &outTest[], // Output 1D array to hold net outputs from training (oldest first)
int ntt, // # of test sets
double &extInitWt[],// Input 1D array to hold 3D array of external initial weights
int numLayers, // # of layers including input, hidden and output
int &lSz[], // # of neurons in layers. lSz[0] is # of net inputs
int AFT, // Type of neuron activation function (0:sigm, 1:tanh, 2:x/(1+x))
int OAF // 1 enables activation function for output layer; 0 disables
);
#import
错误：
所以这意味着dll无法加载和读取 . 那么我有没有办法在我的MQL5程序中包含 .cpp 源文件并使用它？请注意，建议我出路 .
