以编程方式选择一个形状

Question

如何以编程方式（C＃）在SpreadsheetGear中选择一个形状（或图表）？

我曾尝试：

1. IShape.select(false); // failed 
2. ShapeSelection = ...; // failed 

Answer 1

IShape的。 Select（...）是选择形状所需的正确API。我确实看到你在false中通过了“替换”参数，这意味着你将这个新形状添加到已经选择的任何其他形状（即，IWorksheetWindowInfo。ShapeSelection。Count将会是2或更大）。如果您想要替换当前的形状选择，则需要传入true。

下面是一些示例代码，演示了如何在工作表中选择一个或多个形状，并通过一些Console.WriteLine（...）来验证此行为，但我也在SpreadsheetGear的WorkbookView UI上查看这些操作时验证了这种行为控制：

// Create a workbook and a couple shapes on the active worksheet. 
IWorkbook workbook = Factory.GetWorkbook(); 
IWorksheet worksheet = workbook.ActiveWorksheet; 
IShape shape1 = worksheet.Shapes.AddShape(AutoShapeType.Rectangle, 5, 5, 50, 50); 
IShape shape2 = worksheet.Shapes.AddShape(AutoShapeType.Oval, 75, 57, 50, 50); 

// Ensure no shapes are selected. 
IShapeRange shapeSelection = worksheet.WindowInfo.ShapeSelection; 
Console.WriteLine($"ShapeSelection is null? {shapeSelection == null}"); 
// OUTPUT: ShapeSelection is null? True 

// Select shape1 ("Rectangle 1") 
shape1.Select(true); 
shapeSelection = worksheet.WindowInfo.ShapeSelection; 
Console.WriteLine($"ShapeSelection: Count={shapeSelection.Count}, Name[0]={shapeSelection[0].Name}"); 
// OUTPUT: ShapeSelection: Count=1, Name[0]=Rectangle 1 

// Select shape2 ("Oval 2") 
shape2.Select(true); 
shapeSelection = worksheet.WindowInfo.ShapeSelection; 
Console.WriteLine($"ShapeSelection: Count={shapeSelection.Count}, Name[0]={shapeSelection[0].Name}"); 
// OUTPUT: ShapeSelection: Count=1, Name[0]=Oval 2 

// Select both shapes (false passed into IShape.Select(...)) 
shape1.Select(false); 
shapeSelection = worksheet.WindowInfo.ShapeSelection; 
Console.WriteLine($"ShapeSelection: Count={shapeSelection.Count}, Name[0]={shapeSelection[0].Name}, Name[1]={shapeSelection[1].Name}"); 
// OUTPUT: ShapeSelection: Count=2, Name[0]=Oval 2, Name[1]=Rectangle 1
