Answer 1

Try this:

using Excel = Microsoft.Office.Interop.Excel;

1. Collect your ranges into an array:

Excel.Range[] ranges = new Excel.Range[] {yourRange1, yourRange2, ... };

2. Create string-range with ranges addresses and get multi-range from it:

string multiRangeStr = "";
foreach (Excel.Range range in ranges)
{
    string address = range.Address[true, true, Excel.XlReferenceStyle.xlA1];
    multiRangeStr += (multiRangeStr == "" ? "" : ";") + address;
}
//output: multiRangeStr: "A1:A3;B1:B3"

Excel.Range multiRange = wsheet.Range(multiRangeStr);
