我使用的是ZKFinger SDK2.3.3.1版本和Device 通信协议SDK（32位Ver6.2.4.1 - DLL版本：zkemkeeper.dll - 6.2.4.1。我有一个小型USB指纹扫描仪。当我扫描指纹时，
我得到一个字节数组。我将它保存到位图文件中的光盘和jpg两者，指纹看起来非常好扫描。要将指纹模板设置为设备上的用户，我会解压缩指纹图像，然后调用zkemkeeper.dll的SetUserTmp函数。
I am getting size error , (-3) in code.
How can i go further? What is my mistake?
以下是我将手指从USB设备传输到BioMetric设备的代码
bool fullImage = false;
zkfpEng.SaveJPG("Myfirstfinger.jpg");
string strtmp, sRegTemplate;
object pTemplate;
sRegTemplate = zkfpEng.GetTemplateAsStringEx("9");
pTemplate = zkfpEng.DecodeTemplate1(sRegTemplate);
// Note: 10.0Template can not be compressed
zkfpEng.SetTemplateLen(ref pTemplate, 602);
zkfpEng.SaveTemplate("Myfirstfingerprint.tpl", pTemplate);
byte[] TmpData = new byte[700];
TmpData =ObjectToByteArray(pTemplate);
if (bIsConnected == false)
{
MessageBox.Show("Please connect the device first!", "Error");
return;
}
int idwFingerIndex = Convert.ToInt32(cbFingerIndex.Text.Trim());
int idwEnrollNumber = Convert.ToInt32(txtUserID.Text.Trim());
int iTmpLength = 0;
string sdwEnrollNumber = txtUserID.Text.Trim();
axCZKEM1.EnableDevice(iMachineNumber, false);
Cursor = Cursors.WaitCursor;
bool IsSetTmp = false;
IsSetTmp = axCZKEM1.SetUserTmp(iMachineNumber, idwEnrollNumber, idwFingerIndex, ref TmpData[0]);
int errCode = 0;
axCZKEM1.GetLastError(ref errCode);
MessageBox.Show(IsSetTmp.ToString() + " " + errCode.ToString());
if (IsSetTmp == true)
{
MessageBox.Show("User template set successfully!", "Success");
}
else
{
MessageBox.Show("User template not set successfully!", "Error");
}

将指纹图像从设备下载到应用程序的方法。
在此您可以将其上传回其他设备
private void UploadUserInformationAction_Execute(object sender, PopupWindowShowActionExecuteEventArgs e)
{
IObjectSpace os = Application.CreateObjectSpace();
EmployeeBiometric employeeBiometric = (EmployeeBiometric)View.SelectedObjects[0];
EmployeeBiometricParameter param = (EmployeeBiometricParameter)e.PopupWindowViewCurrentObject;
//create new czkemclass obj
CZKEMClass myCZKEMClass = new CZKEMClass();
//connecting the device
myCZKEMClass.Connect_Net(param.Terminal.IPAddress, param.Terminal.Port);
myCZKEMClass.EnableDevice(param.Terminal.DeviceId, false);
int myCount = View.SelectedObjects.Count;
//Set specific user to fingerprint device
for (int i = 1; i <= myCount; i++)
{
int tMachineNo = param.Terminal.DeviceId;
string tEnrollNo = employeeBiometric.Employee.EnrollNo;//Sequence.ToString();
string tName = employeeBiometric.UserName;
string tPassword = employeeBiometric.Password;
int tPrivilege = (int)employeeBiometric.Privilege;
bool tEnabled = employeeBiometric.Enabled;
int tFingerIndex = employeeBiometric.FingerprintIndex;
string tTmpData = employeeBiometric.FingerprintTemplate;
int tFlag = 1;
if (myCZKEMClass.SSR_SetUserInfo(tMachineNo, tEnrollNo, tName, tPassword, tPrivilege, tEnabled))
{
myCZKEMClass.SetUserTmpExStr(tMachineNo, tEnrollNo, tFingerIndex, tFlag, tTmpData);
}
}
myCZKEMClass.RefreshData(param.Terminal.DeviceId);
myCZKEMClass.EnableDevice(param.Terminal.DeviceId, true);
}
