MSVisio字符自定义颜色

Question

我知道，我可以这样改变所有文字的颜色：

Shape.CellsU["Char.Color"].FormulaForceU = "RGB(255,255,255)";

还有一种方法可以通过这种方式改变某些字符的颜色：

Characters.Begin = 2;
Characters.End = 5;    
Characters.set_CharProps((short)MSVisio.VisCellIndices.visCharacterColor, (short)MSVisio.VisDefaultColors.visRed;);

但我找不到任何方法将自定义RGB（或HEX或任何类型）颜色值传递给形状中的某些字符。我不想把形状切成小形状。

你能帮忙吗？谢谢

CharProps属性允许您设置预定义文档颜色集合的索引。对于自定义RGB，您可以通过首先使用CharPropsRow获取行索引来设置相应的单元格公式，如下所示：

    var shp = vApp.ActiveWindow.Selection.PrimaryItem;
    var shpChars = shp.Characters;

    shpChars.Begin = 2;
    shpChars.End = 5;
    //shpChars.set_CharProps((short)Visio.VisCellIndices.visCharacterColor, (short)Visio.VisDefaultColors.visRed);

    var targetRow = shpChars.CharPropsRow[0];
    shp.CellsSRC[(short)Visio.VisSectionIndices.visSectionCharacter, 
                 targetRow,
                 (short)Visio.VisCellIndices.visCharacterColor].FormulaU = "RGB(40,220,40)";

这应该给你类似的结果：

[更新]以上假设您的目标是格式并进行更改。要添加新运行，您可以先使用CharProps添加行，然后使用CharPropsRow来定位新运行。因此，您可以针对新页面运行此代码：

    var vPag = vApp.ActivePage;
    var shp = vPag.DrawRectangle(3,3,5,4);
    shp.Text = "GoodMorning";

    var shpChars = shp.Characters;

    shpChars.Begin = 0;
    shpChars.End = 4;
    var targetRow = shpChars.CharPropsRow[(short)Visio.VisCharsBias.visBiasLetVisioChoose];
    shp.CellsSRC[(short)Visio.VisSectionIndices.visSectionCharacter,
                 targetRow,
                 (short)Visio.VisCellIndices.visCharacterColor].FormulaU = "RGB(220,40,40)";

    shpChars.Begin = 4;
    shpChars.End = 11;
    shpChars.set_CharProps((short)Visio.VisCellIndices.visCharacterColor, (short)Visio.VisDefaultColors.visBlack);
    targetRow = shpChars.CharPropsRow[(short)Visio.VisCharsBias.visBiasLetVisioChoose];
    shp.CellsSRC[(short)Visio.VisSectionIndices.visSectionCharacter,
                 targetRow,
                 (short)Visio.VisCellIndices.visCharacterColor].FormulaU = "RGB(40,200,40)";

......这应该导致以下结果：
