```csharp
using System.Text;
using UnityEditor.Profiling;

public class Example
{
    public static string GetFormattedMetadata(HierarchyFrameDataView frameDataView, int itemId, int mergedSampleIndex)
    {
        int sampleMetadataCount = frameDataView.GetItemMergedSamplesMetadataCount(itemId, mergedSampleIndex);
        if (sampleMetadataCount == 0)
            return null;

        var metadataInfo = frameDataView.GetMarkerMetadataInfo(frameDataView.GetItemMarkerID(itemId));
        var sb = new StringBuilder();
        for (var i = 0; i < sampleMetadataCount; ++i)
        {
            if (metadataInfo != null && i < metadataInfo.Length)
                sb.Append(metadataInfo[i].name);
            else
                sb.Append(i);
            sb.Append(": ");
            sb.Append(frameDataView.GetItemMergedSamplesMetadata(itemId, mergedSampleIndex, i));
            sb.Append('\n');
        }

        return sb.ToString();
    }
}
```

**Throws:**

*System.ArgumentException* if *markerId* is invalid.
