# Load a DICOM image from a byte array in C#

### Image

[Image](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-image.md)

### Bitmap

### SVG

### DICOM

[DICOM](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-dicom.md)

### TIFF

[TIFF](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-tiff.md)

To load a DICOM image from a byte array, use the [`CreateGdPictureImageFromByteArray` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~CreateGdPictureImageFromByteArray.html) of the [`GdPictureImaging` class](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging.html).

This method returns a non-zero GdPicture image identifier (`imageID`) on success. If it fails, it returns `0` — use `GetStat()` to view the failure reason.

Overloads:

- `CreateGdPictureImageFromByteArray(byte[] Data)`

- `CreateGdPictureImageFromByteArray(byte[] Data, DocumentFormat ImageFormat)`

For DICOM byte content, the default overload is typically used so the toolkit auto-detects the format.

If the loaded DICOM has multiple pages/frames, you can use:

- The [`DicomGetPageCount` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~DicomGetPageCount.html)

- The [`DicomSelectPage` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~DicomSelectPage.html)

When you no longer need the image resource, release it with the [`ReleaseGdPictureImage` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~ReleaseGdPictureImage.html).

To load a DICOM image from a byte array, use the following code:

### C#

```csharp

using GdPicture14;
using System;
using System.IO;

using GdPictureImaging gdpictureImaging = new GdPictureImaging();

// Create a byte array from a DICOM file.
byte[] byteArray = File.ReadAllBytes(@"C:\temp\source.dcm");

// Create a GdPicture image from the byte array.
int imageID = gdpictureImaging.CreateGdPictureImageFromByteArray(byteArray);
if (imageID == 0)
{
    Console.WriteLine($"CreateGdPictureImageFromByteArray failed: {gdpictureImaging.GetStat()}");
    return;
}

int pageCount = gdpictureImaging.DicomGetPageCount(imageID);
if (pageCount > 1)
{
    GdPictureStatus selectStatus = gdpictureImaging.DicomSelectPage(imageID, 1);
    if (selectStatus!= GdPictureStatus.OK)
    {
        Console.WriteLine($"DicomSelectPage failed: {selectStatus}");
        gdpictureImaging.ReleaseGdPictureImage(imageID);
        return;
    }
}

GdPictureStatus saveStatus = gdpictureImaging.SaveAsPNG(imageID, @"C:\temp\output.png");
if (saveStatus!= GdPictureStatus.OK)
{
    Console.WriteLine($"SaveAsPNG failed: {saveStatus}");
}

gdpictureImaging.ReleaseGdPictureImage(imageID);

```

### VB.NET

```vb

Imports GdPicture14
Imports System.IO

Using gdpictureImaging As New GdPictureImaging()
    ' Create a byte array from a DICOM file.
    Dim byteArray As Byte() = File.ReadAllBytes("C:\temp\source.dcm")

    ' Create a GdPicture image from the byte array.
    Dim imageID As Integer = gdpictureImaging.CreateGdPictureImageFromByteArray(byteArray)
    If imageID = 0 Then
        Console.WriteLine($"CreateGdPictureImageFromByteArray failed: {gdpictureImaging.GetStat()}")
        Return
    End If

    Dim pageCount As Integer = gdpictureImaging.DicomGetPageCount(imageID)
    If pageCount > 1 Then
        Dim selectStatus As GdPictureStatus = gdpictureImaging.DicomSelectPage(imageID, 1)
        If selectStatus <> GdPictureStatus.OK Then
            Console.WriteLine($"DicomSelectPage failed: {selectStatus}")
            gdpictureImaging.ReleaseGdPictureImage(imageID)
            Return
        End If
    End If

    Dim saveStatus As GdPictureStatus = gdpictureImaging.SaveAsPNG(imageID, "C:\temp\output.png")
    If saveStatus <> GdPictureStatus.OK Then
        Console.WriteLine($"SaveAsPNG failed: {saveStatus}")
    End If

    gdpictureImaging.ReleaseGdPictureImage(imageID)
End Using

```
