Spotfire Automation Xlsx DataWriter

Question

我想知道是否有人在这里尝试创建自动化服务以在Spotfire自动化服务中将DataTable导出到Xlsx？我一直试图创建一个，但我遇到了问题。如果有人能够做到这一点你能分享你的项目吗？

这是我到目前为止的代码，但在访问DataSource和DataTable方面存在问题。

    protected override TaskExecutionStatus ExecuteCore(TaskExecutionContext context)
    {
        DataRowReader dataRowReader;
        ///Create a DataWriter
        DataWriter writer = context.Application.CreateDataWriter(DataWriterTypeIdentifiers.ExcelXlsDataWriter);
        ///<summary>
        ///Call the DataWriter Core from here or call a class that will do the relevant work
        ///<toDO>Need to find a way to access the current DataTable of the Open Analysis</toDo>
        ///</summary>
        Document doc = context.Application.Document;
        if(doc == null)
            return new TaskExecutionStatus(false, "NoAnalysisLoaded");

        DataManager data = doc.Context.GetService<DataManager>();

        DataTable table = data.Tables.Add(doc.ActiveDataTableReference, dataSource);


        string fileName = context.ExpandTags(this.filePath);
        FileStream fs = File.OpenWrite(fileName);
        //See how to properly impliment the writers
        writer.Write(fs, table, new IndexSet(table.RowCount, true), table.Columns.Names);

        fs.Close();
        data.Tables.Remove(table);
        return new TaskExecutionStatus(true);
    }

要获取活动数据表引用，您应该使用

DataTable mytable = Application.Document.ActiveDataTableReference;

然后您可以在代码中进一步使用mytable。
