在Internet Explorer中的边界半径(Border Radius in internet explorer)

 似乎没有内置功能，所以在找到更好的解决方案之前，我将以下方法添加到EPPlus\Drawings\ExcelDrawings.cs 
 
public ExcelShape CloneShape(string SourceName, string TargetName)
{
    if ( _drawingNames.ContainsKey(TargetName.ToLower()))
    {
        throw new Exception("Target name already exists in the drawings collection");
    }

    if (!_drawingNames.ContainsKey(SourceName.ToLower()))
    {
        throw new Exception("Source shape does not exist in the drawings collection");
    }

    ExcelShape shape = new ExcelShape(this, this._drawingsXml,
                               (ExcelShape) this[SourceName]);
    shape.Name = TargetName;
    _drawings.Add(shape);
    _drawingNames.Add(TargetName.ToLower(), _drawings.Count - 1);
    return shape;
}
 
 以及ExcelShape.cs这个构造函数： 
 
internal ExcelShape(ExcelDrawings drawings, XmlDocument DrawingsXml, ExcelShape shapeSource) :
            base(drawings, shapeSource._topNode.Clone(), "xdr:sp/xdr:nvSpPr/xdr:cNvPr/@name")

{
     this.init();
     XmlNode colNode = DrawingsXml.SelectSingleNode("//xdr:wsDr", NameSpaceManager);             
     colNode.AppendChild(this._topNode);
}

Seems like there's no built-in functionality, so until I find a better solution, I added the following method to EPPlus\Drawings\ExcelDrawings.cs
 
public ExcelShape CloneShape(string SourceName, string TargetName)
{
    if ( _drawingNames.ContainsKey(TargetName.ToLower()))
    {
        throw new Exception("Target name already exists in the drawings collection");
    }

    if (!_drawingNames.ContainsKey(SourceName.ToLower()))
    {
        throw new Exception("Source shape does not exist in the drawings collection");
    }

    ExcelShape shape = new ExcelShape(this, this._drawingsXml,
                               (ExcelShape) this[SourceName]);
    shape.Name = TargetName;
    _drawings.Add(shape);
    _drawingNames.Add(TargetName.ToLower(), _drawings.Count - 1);
    return shape;
}
 
and also this constructor in ExcelShape.cs:
 
internal ExcelShape(ExcelDrawings drawings, XmlDocument DrawingsXml, ExcelShape shapeSource) :
            base(drawings, shapeSource._topNode.Clone(), "xdr:sp/xdr:nvSpPr/xdr:cNvPr/@name")

{
     this.init();
     XmlNode colNode = DrawingsXml.SelectSingleNode("//xdr:wsDr", NameSpaceManager);             
     colNode.AppendChild(this._topNode);
}
