基本上你需要注册 IJSRuntime 来调用一个 JS getDimensions()功能

using Microsoft.JSInterop;
using System.Threading.Tasks;

public class BrowserService
{
    private readonly IJSRuntime _js;

    public BrowserService(IJSRuntime js)
    {
        _js = js;
    }

    public async Task<BrowserDimension> GetDimensions()
    {
        return await _js.InvokeAsync<BrowserDimension>("getDimensions");
    }

}

public class BrowserDimension
{
    public int Width { get; set; }
    public int Height { get; set; }
}

JS详情

<script type="text/javascript">
    window.getDimensions = function() {
        return {
                width: window.innerWidth,
                height: window.innerHeight
            };
    };
</script>
