When I call sdk in C#, I got&nbsp;SDKERR\_MODULE\_LOAD\_FAILED, here is the code, could me please help me resolve this as soon as possible, thanks a lot:

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]  
public struct InitParam  
{  
public string strWebDomain;///\< Web Domain  
public string strBrandingName;///\< Branding name  
public string strSupportUrl;///\< Support Url  
public IntPtr hResInstance;///\< resource moudle handle  
public UInt32 uiWindowIconSmallID;///\< windows small icon file path  
public UInt32 uiWindowIconBigID;///\< windows small icon file path  
public SDK\_LANGUAGE\_ID emLanguageID;///\< sdk language ID  
};

static class Program  
{  
[DllImport(@“c:\users\rex\documents\visual studio 2015\Projects\WindowsFormsApplication1\WindowsFormsApplication1\zoom\bin\sdk.dll”, EntryPoint = “InitSDK”, CharSet = CharSet.Unicode, CallingConvention = CallingConvention.Cdecl)]  
public static extern SDKError InitSDK(ref InitParam initParam);

/// \<summary\>  
/// The main entry point for the application.  
/// \</summary\>  
[STAThread]  
static void Main()  
{  
InitParam param = new InitParam();  
param.strWebDomain = “[https://zoom.us](https://zoom.us)”;  
SDKError error = InitSDK(ref param);  
Application.EnableVisualStyles();  
Application.SetCompatibleTextRenderingDefault(false);  
Application.Run(new Form1());  
}  
}

two options to fix this issue.

1.put the sdk dlls into the same folder with exe file.

2.import kernel32 method SetDllDirectory, and config the sdk dlls path

[DllImport(“kernel32.dll”, CharSet = CharSet.Unicode, SetLastError = true, CallingConvention = CallingConvention.Winapi)]  
public static extern bool SetDllDirectory(string lpPathName);

SetDllDirectory(sdk dlls folder path);

//after that, init sdk.
