Google Sheets SortSpecs

问题

I'm trying to create a request for Google Sheets, but I'm having problems with the sortSpecs method.

var test = new Request()
        {
            SortRange = new SortRangeRequest()
            {
                Range = new GridRange()
                {
                    SheetId = 0,
                    StartRowIndex = 1                        
                },
                SortSpecs = new SortSpec()
                {
                    SortOrder = "ASCENDING",
                    DimensionIndex = 0
                }
            }
        };

When using this, everything works correctly except for the SortSpec. Visual Studio gives the error:

Cannot implicitly convert type 'Google.Apis.Sheets.v4.Data.SortSpec' to System.Collections.Generic.IList' An explicit conversion exists

UPDATE:

There are no more build errors, but now I have another error when executing the code.

        List<Data.Request> requests = new List<Data.Request>();  // TODO: Update placeholder value.

        Data.SortSpec so = new Data.SortSpec();
        so.SortOrder = "ASCENDING";

        Data.SortSpec di = new Data.SortSpec();
        di.DimensionIndex = 0;

        List<Data.SortSpec> ss = new List<Data.SortSpec>();
        ss.Add(so);
        ss.Add(di);

        var test = new Request()
        {
            SortRange = new SortRangeRequest()
            {
                Range = new GridRange()
                {
                    SheetId = 0,
                    StartRowIndex = 1
                },
                SortSpecs = ss
            }

        };

        requests.Add(test);

The exception given is

Message[Invalid requests[0].sortRange: No sort order specified.] Location[ - ] Reason[badRequest] Domain[global]

Per the reference docs, SortSpecs is a list of items, not a single item. The error message is also saying that (it can't convert SortSpec to an IList). If you want to use a single SortSpec for your sorting specifications, create a list, put that single item in it, and assign SortSpecs to that list.

Looks like you are instantiating 2 new SortSpec objects but you just need 1 object instantiation and assign values to 2 of it's fields "SortOrder" and "DimentionIndex". I had same sheet sorting requirement and I was able to solve it this way:

        BatchUpdateSpreadsheetRequest reqbody = new BatchUpdateSpreadsheetRequest();
        SortSpec ss = new SortSpec();
        ss.DimensionIndex = 1;
        ss.SortOrder = "ASCENDING";

        GridRange rangetosort = new GridRange();
        rangetosort.StartColumnIndex = 0;
        rangetosort.EndColumnIndex = 12;
        rangetosort.StartRowIndex = 2;
        rangetosort.EndRowIndex = totalrows;
        rangetosort.SheetId = sheetgid;

        SortRangeRequest srr = new SortRangeRequest();
        srr.Range = rangetosort;
        IList<SortSpec> sortspecs = new List<SortSpec>();
        sortspecs.Add(ss);
        srr.SortSpecs = sortspecs;
        Request req1 = new Request();
        req1.SortRange = srr;
        IList<Request> req2 = new List<Request>();
        req2.Add(req1);
        reqbody.Requests = req2;

        SpreadsheetsResource.BatchUpdateRequest sortreq = sheetsrv1.Spreadsheets.BatchUpdate(reqbody, spid);
        try
        {
            sortreq.Execute();
            Console.WriteLine("Sorting Operation successfull");
        }
        catch(Exception ex6)
        {
            Console.WriteLine(ex6.Message);
        }
