Question

I want to have mutple format types in one cell in my workbook. For example I want my A1 cell to display \" Name: Aaron Kruger \". When I programmatically

Answer 1

I recorded a macro, it shouldn't be hard to translate it to C#:

ActiveCell.FormulaR1C1 = "Test test"
Range("A1").Select
ActiveCell.FormulaR1C1 = "Test test"
With ActiveCell.Characters(Start:=1, Length:=5).Font
    .Name = "Calibri"
    .FontStyle = "Regular"
    .Size = 11
    .Strikethrough = False
    .Superscript = False
    .Subscript = False
    .OutlineFont = False
    .Shadow = False
    .Underline = xlUnderlineStyleNone
    .ThemeColor = xlThemeColorLight1
    .TintAndShade = 0
    .ThemeFont = xlThemeFontMinor
End With
With ActiveCell.Characters(Start:=6, Length:=4).Font
    .Name = "Calibri"
    .FontStyle = "Bold"
    .Size = 11
    .Strikethrough = False
    .Superscript = False
    .Subscript = False
    .OutlineFont = False
    .Shadow = False
    .Underline = xlUnderlineStyleNone
    .ThemeColor = xlThemeColorLight1
    .TintAndShade = 0
    .ThemeFont = xlThemeFontMinor
End With

Use Microsoft.Office.Interop.Excel.Range which gives you each character as Characters type. Now use its Font and other properties to style them.

Refer an example here: http://www.bloodforge.com/post/Extract-Formatted-Text-From-Excel-Cell-With-C.aspx

 Microsoft.Office.Interop.Excel.Range Range = (Microsoft.Office.Interop.Excel.Range)Cell;
   int TextLength = Range.Text.ToString().Length;
   for (int CharCount = 1; CharCount <= TextLength; CharCount++)
   {
       Microsoft.Office.Interop.Excel.Characters charToTest = Range.get_Characters(CharCount, 1);
       bool IsBold = (bool)charToTest.Font.Bold;
       bool IsItalic = (bool)charToTest.Font.Italic;
       // other formatting tests here

   }

Answer 3

Range rng1 = ws.getRange("A1","E10");
for(int i=0;i<10;i++)
{
    Range rngTst=rng.cells[i,i];
    for(int j=0;j<rngTst.get_characters().count;j++)
    {
        rngTst.application.activecell.get_characters(j,j).font.color
    }
}

or

int sFirstFoundAddress = currentFind.FormulaR1C1Local.ToString().IndexOf("NOT FOR CIRCULATION ");

get_Range(excel.Cells[1, 1],
    excel.Cells[1, dtData.Columns.Count])
        .get_Characters(sFirstFoundAddress, 20).Font.Color =
            System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
