Question

I am currently developing an application to work with WAV files. I want to be able to display the information in the struct with its native type, but C# thinks of char as a 16 bit value.

The four bytes ChunkID0…3 are supposed to contain ‘R’ ‘I’ ‘F’ ‘F’

[StructLayout(LayoutKind.Explicit, Size = 12, Pack = 1)]
public unsafe struct RiffDescriptor
{
    [FieldOffset(0)]
    public byte ChunkID_0;

    [FieldOffset(1)]
    public byte ChunkID_1;

    ...
}

I want the debugger to show the ChunkID as ‘R’ instead of 122.

Any thoughts?

public class RiffDescriptor
{
    public RiffDescriptor(BinaryReader b)
    {
        // Read the ChunkID - Should be RIFF
        ChunkID = b.ReadBytes(4);

        // Read the ChunkSize
        ChunkSize = b.ReadUInt32();

        // Read the Format - Should be WAVE
        Format = b.ReadBytes(4);
    }

    [DebuggerDisplay("ChunkID = {System.Text.Encoding.Default.GetString(ChunkID)}")]
    public byte[] ChunkID;

    public UInt32 ChunkSize;

    [DebuggerDisplay("Format = {System.Text.Encoding.Default.GetString(Format)}")]
    public byte[] Format;
}
