Merage

AE+C# 实现MERGE,

代码参考ESRI中国社区，忘了哪个帖子了。。。
代码中路径等直接写上去了

            //合并图层的集合
            ILayer pLayer;
            IArray pArray;
            pArray = new ArrayClass();
            for (int i = 0; i < this.axMapControl1.LayerCount; i++)

                pArray.Add(pLayer);
               }
            //定义输出图层的fields表

            pTable = (ITable)pLayer;
            pFeatureLayer=(IFeatureLayer)pLayer;
            pFeatureClass = pFeatureLayer.FeatureClass;

            //判断图层是否大于2个
            if(this.axMapControl1.LayerCount< 2)
             {
                MessageBox.Show("Table QI failed");
                return;
              }
