I use ClosedXML nuget package to read excel content from stream. It has a constructor overload in XLWorkbook class which takes stream pointing to an excel file (aka workbook).

imported namespace at the top of your code file:

using ClosedXML.Excel;

Source code:

var stream = /*obtain the stream from your source*/;
if (stream.Length != 0)
{
    //handle the stream here
    using (XLWorkbook excelWorkbook = new XLWorkbook(stream))
    {
        var name = excelWorkbook.Worksheet(1).Name;
        //do more things whatever you like as you now have a handle to the entire workbook.
        var firstRow = excelWorkbook.Worksheet(1).Row(1);
    }
}
