run matlab script that process series of images in visual studio(c# language)?

using following Matlab code I have successfully load the images in folder (location:F:\anuradha) but when it is run through visual studio (c# language) results were not obtained. can anyone help me????

%code_01  
filePattern1 = fullfile('F:\anuradha\', '*.jpg');
  imagefiles1 = dir(filePattern1);

it should be mention here I have create object in C# and the matlab script is passed in to string the following code gives more explanation

string mScript;
MLApp.MLApp matlab = new MLApp.MLApp();
      private void loadMScript_segment()
      {

            System.IO.StreamReader myFile =
                        new System.IO.StreamReader("F:\\anuradha\\resizeing.m");

            mScript = myFile.ReadToEnd();

            myFile.Close();
        }
        private void buttonsgmnt_Click(object sender, EventArgs e)
        {
            loadMScript_segment();
            matlab.Execute(mScript);
        }

here resizeing.m is the matlab script which is included * _ code_01_* mention above

here it is not the case of execution pattern. it gives error at the matlab script, which is mention below.

%resizeing.m
 filePattern1 = fullfile('F:\anuradha\', '*.jpg');
 imagefiles1 = dir(filePattern1);
 imagefiles1 = dir(filePattern1);
 nfiles1 = length(imagefiles1);
 for jj=1:nfiles1
    currentfilename1 = imagefiles1(jj).name;
    currentimage1 = imread(currentfilename1);
    images{jj} = currentimage1; 
    b = currentimage1;
    figure;
    imshow(b);
    hold on;
 end

according to the above code it should be display all image inside the folder after run the c# code

Why not just simply execute

matlab.Execute("run F:\\anuradha\\resizeing.m")

[Sahan Priyanga]

i think it is not the case in execution pattern. it fails at the matlab script

[Image Analyst]

So it fails in the MATLAB code, not the C code. Well, you forgot to post the MATLAB error text. Please copy and paste all the error code that you see. Can you run the MATLAB code entirely from within MATLAB successfully?

You did not take into account that you might not be cd'd to the correct directory.

 %resizeing.m
 projectdir = 'F:\anuradha';
 filePattern1 = fullfile(projectdir, '*.jpg');
 imagefiles1 = dir(filePattern1);
 nfiles1 = length(imagefiles1);
 for jj=1:nfiles1
    currentfilename1 = fullfile(projectdir, imagefiles1(jj).name);
    currentimage1 = imread(currentfilename1);
    images{jj} = currentimage1; 
    b = currentimage1;
    figure;
    imshow(b);
    hold on;
 end
