我正在研究Word AddIns和使用Interop libraryof Word，我想为 Shape 分配一个名称（字符串），但 word.shape.name 抛出异常：

“System.UnauthorizedAccessException：访问被拒绝。（来自 HRESULT 的异常：0x80070005 (E_ACCESSDENIED)）”。

我的代码是：

        bool blnRetVal = false;
        string strModel = ndModel.Name;
        int lngModel = 0;
        int lngNextModel = 0;
        int lngStart;
        int lngEnd;
        Alias.Document objTemp;
      Microsoft.Office.Interop.Word.Range objRange;
        Shape objShape;
        Object[] astr;
        int n;
        bool bLastModel;
        /*'--------------------------------------------------------------------------------------------------
        '   1. Find model's model marker and the next marker (if any)

        astr = dicMarkers.Keys();
        for (n = astr.GetLowerBound(0); n <= astr.GetUpperBound(0); n++)
        {
            if (string.Compare(astr[n].ToString(), strModel, true) == 0)
            {
                lngModel = (int)dicMarkers.get_Item(astr[n]);   //PNDC  //dicMarkers.Item(astr(n))
                if (n < astr.GetUpperBound(0))
                {
                    if (string.Compare(astr[n + 1].ToString(), "#end", true) == 0)
                    {
                        lngNextModel = 0;
                        bLastModel = true;
                    }
                    else

我无法复制您的错误，但是我可以通过一些更改让您的代码运行。让我知道我是否误解了。

请注意Missing使用的变量而不是objRange. 我还删除了不适用的变量。

using Word = Microsoft.Office.Interop.Word;
using Alias = Microsoft.Office.Interop.Word;

public Test()
{
    var doc = new Alias.Document();
    var doc2 = new Alias.Document();
    var t = this.CloneModel(ref doc, ref doc2);
}
private bool CloneModel(ref Alias.Document objTargetDocument, ref Alias.Document objSourceDocument)
{
    var missing = Type.Missing;
    Word.Shape objShape;
    objShape = objTargetDocument.Shapes.AddTextbox(
        Microsoft.Office.Core.MsoTextOrientation.msoTextOrientationUpward, 0, 0, 0, 0, ref missing); <== note the missing here instead of objRange

    objShape.Name = "Carma DocSys~Brief"; // no longer throwing exceptions (hard coded string)
    objShape.Visible = Microsoft.Office.Core.MsoTriState.msoFalse;
    return true;
}

如果这不是问题，那么我建议您在文件权限方面遇到问题，如错误消息所示。
