以字节为单位获取资源[] C＃

Question

I'm trying to get an image in the resources as a byte[] for insertion into a database. The resource is at Resources/CatSeal and is a file called index.jpg.

I've looked at this question , but I'm still having trouble. I'm getting a NullReferenceException on the indicated line. My namespace is DatabaseConnectionTests . According to this documentation , under "Access Resources" it should follow this format, which I believe I'm doing:

MyNameSpace.MyImage.bmp

Here's my code:

Stream sourceStream = Assembly.GetExecutingAssembly().GetManifestResourceStream("DatabaseConnectionTests.index.jpg");
using (var memoryStream = new MemoryStream())
{
    sourceStream.CopyTo(memoryStream); // NullReferenceException here
    seal.SealerImage = memoryStream.ToArray();
}
sealDatabaseOperations.Insert(seal);

How can I resolve this so that my resource image is loaded to a byte[] ? Thanks in advance.

Looks like it's not finding your resource.

Try: "DatabaseConnectionTests.Resources.index.jpg"

Set a breakpoint in a class in the same assembly and evaluate this:

this.GetType().Assembly.GetManifestResourceNames()

That will list all resource names avail for that assembly.
