公共 API Aspose.Cells 9.0.0 的变化

添加的 API

添加了 Shape.TextOptions 属性

Aspose.Cells for .NET 公开了 Shape 类的 TextOptions 属性,以控制 Shape 文本部分的外观。

这是 Shape.TextOptions 属性的简单使用场景。

C#

 // Initialize an instance of Workbook

var book = new Workbook();

// Get the default Worksheet from the Workbook

var sheet = book.Worksheets[0];

// Add a TextBox to the collection

var textboxIndex = sheet.TextBoxes.Add(2, 1, 160, 200);

// Get the TextBox object

var textbox = sheet.TextBoxes[textboxIndex];

// Add text to the TextBox

textbox.Text = "Hello Aspose!";

// Format the textual contents

textbox.TextOptions.Color = System.Drawing.Color.Red;

textbox.TextOptions.IsItalic = true;

添加了 LoadOptions.CultureInfo 属性

Aspose.Cells for .NET 9.0.0 公开了 LoadOptions.CultureInfo 属性,允许在工作簿实例中加载文档时注入 CultureInfo 实例。

这是上述属性的简单使用场景。

C#

 // Create an instance of CultureInfo and populate its properties

var culture = new CultureInfo("en-GB");

culture.NumberFormat.NumberDecimalSeparator = ",";

culture.DateTimeFormat.DateSeparator = "-";

culture.DateTimeFormat.ShortDatePattern = "dd-MM-yyyy";

// Create an instance of LoadOptions and set the CultureInfo property

var options = new LoadOptions(LoadFormat.Html);

options.CultureInfo = culture;

// Load a HTML or TXT file in an instance of Workbook with instance of  LoadOptions

var book = new Workbook(dir + "input.html", options);

添加了 ChartPoint.IsInSecondaryPlot 属性

Aspose.Cells for .NET 公开了 ChartPoint.IsInSecondaryPlot 属性,该属性可用于检测 ChartPoint 是否驻留在饼图或条形图的辅助图上。

下面是 Shape.Line 属性的简单使用场景。

C#

 // Load an existing spreadsheet containing a Pie chart

var book = new Workbook(dir + "PieBar.xlsx");

// Load the Worksheet at 0 index

var sheet = book.Worksheets[0];

// Load the first chart from the collection

var chart = sheet.Charts[0];

// Calculate the chart before accessing its properties

chart.Calculate();

// Accessing chart's first series

var series = chart.NSeries[0];

// Loop over the ChartPoint collection

foreach (ChartPoint point in series.Points)

{

    // Detect if ChartPoint resides on secondary plot

    Console.WriteLine(point.IsInSecondaryPlot);

}

添加了 OleObject.ClassIdentifier 属性

Aspose.Cells for .NET 9.0.0 公开了 OleObject.ClassIdentifier 属性,可用于指定加载 OleObject 的应用程序行为。例如,一个 PPT 文件可以嵌入到具有 2 个不同视图的电子表格中,即;演示视图或幻灯片视图,而这两个视图具有不同的类标识符值。

以下是 OleObject.ClassIdentifier 属性的简单使用场景。

C#

 // Load a spreadsheet containing a presentation as OleObject

var book = new Workbook(dir + "embeddedPresentation.xls");

// Initialize variables to store properties of OleObject

int upperLeftRow = 0;

int upperLeftColumn = 0;

int height = 0;

int width = 0;

byte[]imageData = null;

int x = 0;

int y = 0;

byte[]objData = null;

string progID = "";

FileFormatType fileFormatType = FileFormatType.Unknown;

string sourceFullName = "";

bool isDisplayAsIcon = false;

byte[]classId = null;

// Get the first worksheet from the collection

var sheet = book.Worksheets[0];

// Get the first OleObject from the collection

var frame = sheet.OleObjects[0];

// Store the properties in variables

upperLeftRow = frame.UpperLeftRow;

upperLeftColumn = frame.UpperLeftColumn;

height = frame.Height;

width = frame.Width;

imageData = frame.ImageData;

x = frame.X;

y = frame.Y;

objData = frame.ObjectData;

progID = frame.ProgID;

fileFormatType = frame.FileFormatType;

sourceFullName = frame.ObjectSourceFullName;

isDisplayAsIcon = frame.DisplayAsIcon;

classId = frame.ClassIdentifier;

// Initialize a new Workbook instance

book = new Workbook();

// Access first worksheet from the collection

sheet = book.Worksheets[0];

// Insert the OleObject to the worksheet

int oleNumber = sheet.OleObjects.Add(upperLeftRow, upperLeftColumn, height, width, imageData);

// Access newly inserted OleObject

var embeddedObject = sheet.OleObjects[oleNumber];

// Assign previously stored properties to new OleObject

embeddedObject.X = x;

embeddedObject.Y = y;

embeddedObject.ObjectData = objData;

embeddedObject.ProgID = progID;

embeddedObject.FileFormatType = fileFormatType;

embeddedObject.DisplayAsIcon = isDisplayAsIcon;

embeddedObject.ObjectSourceFullName = sourceFullName;

embeddedObject.IsAutoSize = false;

if (classId != null)

{

    embeddedObject.ClassIdentifier = classId;

}

// Save the resultant spreadsheet

book.Save(dir  + "output.xls");
