是否可以从Microsoft.Office.Interop.Excel.ApplicationClass确定Excel是在32位还是64位上运行?
编辑该解决方案应适用于Excel 2010和Excel 2007
最佳答案
此代码应为您提供Excel的“便利性”。
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:这是另一个版本,也应该适用于早期版本的Excel。只需传递一个ApplicationClass引用即可:
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
}
