Have you tried, 
File 
Save As
Save as type (down at the drop-down)
and *.pdf

For me that converts the textbox and the triangle as well. 

Put it on a single button and works for me with referencing:

<pre><code>using Excel = Microsoft.Office.Interop.Excel

Excel.Application xlApp = new Excel.Application();
 Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"H:\My Documents\Fun\tri.xlsx");
 xlWorkbook.ExportAsFixedFormat(Excel.XlFixedFormatType.xlTypePDF, @"H:\My Documents\Fun\tri.pdf");
</code></pre>

 Workbook workBook = null;
 try

 workBook = application.Workbooks.Open(sourcePath, missing, missing, missing, missing, missing,

 }
</code></pre>

Add the Reference as "Microsoft.Office.Interop.Excel" and after adding this, Right click the "Microsoft.Office.Interop.Excel" and select properties, and change "Embed Interop Types" to false

And you can call the method as like below

<pre><code>ConvertToPDF(@"D:\WithImage_Shapes.xlsx", @"D:\WithImage_Shapes.pdf", XlFixedFormatType.xlTypePDF);
