本文介绍了查找位数(32位/ 64位)从Excel应用程序对象?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
是否有可能确定在从Microsoft.Office.Interop.Excel.ApplicationClass 32位或64位的Excel是否运行?
修改的
应该为Excel 2010和Excel 2007中的解决方案
Is it possible to determine whether Excel is running in 32-bit or 64-bit from the Microsoft.Office.Interop.Excel.ApplicationClass?
Edit
The solution should work for both Excel 2010 and Excel 2007
推荐答案
这code应该给你的Excel的位数。
This code should give you the "bitness" of Excel.
Microsoft.Office.Interop.Excel.ApplicationClass app = new Microsoft.Office.Interop.Excel.ApplicationClass();
if (System.Runtime.InteropServices.Marshal.SizeOf(app.HinstancePtr) == 8)
{
// excel 64-bit
}
else
{
// excel 32-bit
}
编辑:这是另一个应为Excel的previous版本以及工作版本。只是传递一个ApplicationClass参考吧:
here is another version that should work for previous versions of Excel as well. Just pass an ApplicationClass reference to it:
public static ExcelVersion GetExcelVersion(object applicationClass)
{
if (applicationClass == null)
throw new ArgumentNullException("applicationClass");
PropertyInfo property = applicationClass.GetType().GetProperty("HinstancePtr", BindingFlags.Instance | BindingFlags.Public);
if (property == null)
return ExcelVersion.Excel;
return (System.Runtime.InteropServices.Marshal.SizeOf(property.GetValue(applicationClass, null)) == 8) ? ExcelVersion.Excel2010_64 : ExcelVersion.Excel2010_32;
}
public enum ExcelVersion
{
Excel, // before 2010, so 32 bits
Excel2010_32,
Excel2010_64
}
