如何将 System.Drawing.Color 转换为 Microsoft Interop WdColorIndex [英] How to convert System.Drawing.Color to Microsoft Interop WdColorIndex

问题描述

如何将 System.Drawing.Color 转换为 Microsoft.Office.Interop.Word.WdColorIndex?

到目前为止我已经完成了代码，但它显示了溢出"错误.

I have done the code so far, but it's showing the error "overflow".

这是我做的代码

Color bgcolor = Color.FromArgb(Convert.ToInt32(innerText));
Microsoft.Office.Interop.Word.WdColorIndex wbgc = (Microsoft.Office.Interop.Word.WdColorIndex)(bgcolor.R + 0x100 * bgcolor.G + 0x10000 * bgcolor.B);
doc.Range(iRangeStart, iRangeEnd).HighlightColorIndex = wbgc;

我怎样才能做到这一点?

How can I achieve this?

推荐答案

WdColorIndex 是一个枚举，而不是一个定义颜色系统的对象.这意味着您可以分配的值受枚举元素的限制，例如wdBlack 或 wdBlue 及其基础整数值.

WdColorIndex is an enumeration, not an object that defines a color system. This means that the value you can assign is limited by the enumeration elements, e.g. wdBlack or wdBlue and their underlying integer values.

您使用的技术是应用于 WdColor 对象而不是 WdColorIndex 枚举:

The technique you are using is to be applied to a WdColor object instead of a WdColorIndex enumeration:

var wordColor = (Microsoft.Office.Interop.Word.WdColor)(bgcolor.R + 0x100 * bgcolor.G + 0x10000 * bgcolor.B);

Word 文档中的突出显示仅限于多种颜色，如 WdColorIndex 枚举中所定义.因此，您不能简单地将任何颜色转换为 Word 颜色以进行突出显示.您必须选择可用值之一.有关可能的值，请参阅 MSDN for WdColorIndex.

Highlighting in a Word document is limited to a number of colors, as defined in the WdColorIndex enumeration. Therefore, you cannot simply convert any color to a Word color for highlighting. You have to pick one of the available values. See MSDN for WdColorIndex for possible values.
