非静态的字段、方法或属性“ESRI.ArcGIS.Carto.IMapDocument.DocumentFilename.get”要求对象引用
请出现这种错误是为什么呢 该如何改正呢

--------------------编程问答-------------------- 是从下面这一段开始出现问题 上面那一段代码调试是没有问题的
请问问什么这样呢
private void saveToolStripMenuItem_Click(object sender, EventArgs e)
{
if (MapDocument.get_IsReadOnly(MapDocument.DocumentFilename) == true)
{
MessageBox.Show("地图文档是只读的无法保存");
}
string fileSavePath=@"e:\new.mxd";
try
{
MapDocument .Save(MapDocument .UsesRelativePaths,true );
MessageBox.Show ("保存地图文档成功");
}
catch (Exception e)
{
MessageBox .Show ("保存地图文档失败！！！"+e.ToString());
}
--------------------编程问答-------------------- MapDocument如果是类的话，要改成这个类的对象 --------------------编程问答-------------------- 看看 你的ArcGIS 是不是引用完全 地图方法和控件是不是引用正确 这几个方法是GIS封装好的 你的错误5把e换成ex就行 --------------------编程问答-------------------- 上面的问题已经解决了 也可以调试 但是我点击Save的时候在红色字体代码那里出现了下面的图片上的错误 是什么原因呢

--------------------编程问答-------------------- 最后的问题楼主解决了吗？遇到同样的问题了
补充：.NET技术 , C#
