The type initializer for 'DPFP.Verification.Verification' threw an exception

i got the error on this line
DPFP.Verification.Verification ver = new DPFP.Verification.Verification();
The type initializer for 'DPFP.Verification.Verification' threw an exception.

actually i m performing verification process to match fingerprint from the database and given finger

code is here

//database code

 Byte fpBytes;

MemoryStream MemStream = new MemoryStream(data);//use for given finger

DPFP.FeatureSet features =

ExtractFeatures(MemSample,DPFP.Processing.DataPurpose.Verification);

// at this line it throw exception
DPFP.Verification.Verification ver = new DPFP.Verification.Verification();

DPFP.Verification.Verification.Result res = new DPFP.Verification.Verification.Result();

                DPFP.Template Templ1 = new Template();

                Templ1.DeSerialize(MemStream);



                foreach (DataRow row in temp.Rows)

                {

                    fpBytes = (byte)row["bio"];

                    MemoryStream ms = new MemoryStream(fpBytes);



                    DPFP.Template Templ = new Template();

                    Templ.DeSerialize(ms);





                    if (Templ1 != null)

                    {



                        // Compare feature set with particular template.

                        ver.Verify(features, Templ, ref res);



                        d.IsFeatureSetMatched = res.Verified;

                        d.FalseAcceptRate = res.FARAchieved;
