Question

我有以下代码，但我一直收到错误＆＃34;无法插入OpenXmlElement＆＃34; newChild＆＃34;因为它是树的一部分＆＃34;

private static Stylesheet CreateStylesheet()
    {
        Stylesheet ss = new Stylesheet();
        //ESTILO PARA CELDA F6


        Fills fill1 = new Fills();

        GradientFill gfill = new GradientFill() { Type = GradientValues.Path, Degree = 45, Left=0.2, Right= 0.8, Top=0.2, Bottom = 0.8 };
        GradientStop sfill1 = new GradientStop() { Position = 0, Color = new Color() { Theme = 0 }  };
        fill1.Append(fill);
        fill1.Append(gfill);

        fill1.Append(fill4);
        fill1.Append(gfil4);
        fill1.Append(sfill4);



        //ESTILO DE BORDE PARA INGRESAR UNA CELDA EN EL METODO ASIGNACELDA

        //INDEX 0
        Borders brs = new Borders();

        //ALINEACIÓN PARA EL CELL FORMAT DE CELDA GENERAL EN ASIGNACELDA

        Alignment al = new Alignment() { WrapText = true , Vertical = VerticalAlignmentValues.Center};

       //ALIENACIÓN PARA VALIDACION DE LFA Y LIA

        //INDEX 0 ESTILO GENERALA DE ALTAS
        CellFormat cel = new CellFormat() {  Alignment = al , BorderId = 0  };



//Here's where the error is generated
-->        CellFormat cel2 = new CellFormat() { Alignment = al , FillId =2 , BorderId = 0 };

"           --- en este segmento es donde manda la expection "

        //INDEX 2 ESTILO  DE ANUAL
        CellFormat cel3 = new CellFormat() { Alignment = al, FillId = 3, BorderId = 0 };


        //INDEX 3 ESTILO PARA INSERTCELLSPECIAL
        CellFormat cel4 = new CellFormat() { NumberFormatId = 0 };

        //INDEX 4 ESTILO PARA VALIDACION LFA Y LIA
        CellFormat cel5 = new CellFormat() { Alignment = al2 };

        cells.Append(cel);
        cells.Append(cel2);
        cells.Append(cel3);
        cells.Append(cel4);
        cells.Append(cel5);



        return ss;

    }

你有什么想法吗？我发现了一个具有相同错误的主题但由于某种原因它对我不起作用。任何帮助是极大的赞赏。

问题在于Alignment对象被分配到cel2（和cel3）。该对象的相同实例被分配给cel，cel2和cel3，这意味着该实例将与XML树的不同部分相关联。是不允许的。

要解决此问题，您需要为您创建的每个Aligment对象分配CellFormat类的新实例。他们可以共享相同的属性;他们只需要成为不同的实例。

您可以通过显式创建新实例或使用Clone方法创建Alignment对象的副本来执行此操作。

例如：

Alignment al = new Alignment() { WrapText = true, Vertical = VerticalAlignmentValues.Center };

//safe to use al
CellFormat cel = new CellFormat() { Alignment = al, BorderId = 0 };

//can't use al but we can use a clone of it
CellFormat cel2 = new CellFormat() { Alignment = (Alignment)al.Clone(), FillId = 2, BorderId = 0 };

//this time we're explicitly creating a new Alignment but we could have used clone again
CellFormat cel3 = new CellFormat() { Alignment = new Alignment() { WrapText = true, ShrinkToFit = true }, FillId = 3, BorderId = 0 };
