利用C#在Word自动化中操作OLE控件

因项目所需，采用WORD模板作为报表系统的一部分，需要使用C#操作WORD文档，大部分的操作都是填充表格，难度也不是很大。但是有一份报表很特殊，WORD里面需要包含ComboBox、CheckBox控件，如下所示：


这里关键的技术难题是找到OLE控件，然后设置其某个属性值，GOOGLE了半天，终于找到如下的代码：

private static object FindControl(string name, Word._Document document)
        {
            try
            {
                foreach (Word.InlineShape shape in document.InlineShapes)
                {
                    if (shape.Type ==Word.WdInlineShapeType.wdInlineShapeOLEControlObject)
                    {
                        object oleControl = shape.OLEFormat.Object;
                        Type oleControlType = oleControl.GetType();
                        string oleControlName = (string)oleControlType.InvokeMember("Name",
                            System.Reflection.BindingFlags.GetProperty,null, oleControl, null);
                        if (String.Compare(oleControlName, name, true,System.Globalization.CultureInfo.InvariantCulture) == 0)
                        {
                            return oleControl;
                        }
                    }
                }

                foreach (Word.Shape shape in document.Shapes)
                {
                    if (shape.Type ==Microsoft.Office.Core.MsoShapeType.msoOLEControlObject)
                    {
                        object oleControl = shape.OLEFormat.Object;
                        Type oleControlType = oleControl.GetType();
                        string oleControlName = (string)oleControlType.InvokeMember("Name",
                            System.Reflection.BindingFlags.GetProperty,null, oleControl, null);
                        if (String.Compare(oleControlName, name, true,System.Globalization.CultureInfo.InvariantCulture) == 0)
                        {
                            return oleControl;
                        }
                    }
                }
            }
            catch
            {
                // Returns null if the control is not found.
            }
            return null;
        }

找到OLE控件后，经过尝试，发现设置其属性时，应该如下调用：

oleControlType.InvokeMember("Value", System.Reflection.BindingFlags.SetProperty, null, oleControl, new object[] { "True" });
