I am getting following error while compressing the dcm file on following line.

ImageReader reader = new ImageReader();

Error:

The type initializer for 'gdcm.gdcmPINVOKE' threw an exception.

How to resolve this Error?

I am using gdcm-sharp.dll for compressing the file.

What I have tried:

I am using gdcm-sharp.dll for compressing the file.

I am posting my Code here:
private void button1_Click(object sender, EventArgs e)
{
string inputFileNamepath = @"G:\Test\Test_07_06_2016\Source\BU001015MN-166-CL-001V01_2005101414120923_1_1.dcm";
string outputFileNamepath =@"G:\Test\Test_07_06_2016\Source1\GDCMBU001015MN-166-CL-001V01_2005101414120923_1_1.dcm";

//FileInfo file = new FileInfo(@"G:\Test\Test_07_06_2016\Source\BU001015MN-166-CL-001V01_2005101414120923_1_1.dcm");

string extension = Path.GetExtension(inputFileNamepath);
inputFileNamepath = Path.GetFileName(inputFileNamepath);

outputFileName = Path.GetFileName(outputFileNamepath);

try
{
ImageReader reader = new ImageReader();//getting error on this file
reader.SetFileName(inputFileName);

if (!reader.Read())
{
MessageBox.Show("Cannot Read the file:-" + inputFileName);
return;
}

gdcm.File file = reader.GetFile();

gdcm.DataSet ds = file.GetDataSet();
gdcm.Image image = reader.GetImage();

ImageChangeTransferSyntax change = new ImageChangeTransferSyntax();
TransferSyntax targets = new TransferSyntax(TransferSyntax.TSType.JPEGBaselineProcess1);
change.SetTransferSyntax(targets);

JPEGCodec codec = new JPEGCodec();

if(!codec.CanCode(targets))
{
MessageBox.Show("WrongData");
return;
}
codec.SetLossless(false);
codec.SetQuality(50);
change.SetUserCodec(codec);
change.SetInput(image);

bool b = change.Change();

if (!b)
{
MessageBox.Show("Can not change Ttansfer Syntax");
return;
}

ImageWriter writer = new ImageWriter();
writer.SetImage((gdcm.Image)change.GetOutput());
writer.SetFile(reader.GetFile());
writer.SetFileName(outputFileName);

if (!writer.Write())
{
MessageBox.Show("Could not write");
}
