ArcEngine 图例C#源码:
private void MakeLegend(IActiveView activeView,IPageLayout pageLayout)
{
//定义图例UID对象
UID uid = new UIDClass();
uid.Value="esriCore.Legend";
//设置图例存放的坐标位置
//定义单位
pageLayout.Page.Units = esriUnits.esriCentimeters;
//得到草图容器对象
IGraphicsContainer container = pageLayout as IGraphicsContainer;
//得到当前地图的框架
IMapFrame frameElement = container.FindFrame(activeView.FocusMap) as IMapFrame;
IElement mapElement = frameElement as IElement;
IEnvelope mapEnv = mapElement.Geometry.Envelope;
IEnvelope envelope = new EnvelopeClass();
//通过当前地图框架得到相对位置
envelope.PutCoords(mapEnv.XMin, mapEnv.YMin, mapEnv.XMin + 6.5, mapEnv.YMin + 0.8);
IMapSurroundFrame frame = frameElement.CreateSurroundFrame(uid, null);
ILegend legend = frame.MapSurroun

很多时候有一个xml字符串，没有换行，没有缩进，要生成xml文件不易阅读。下面的代码就是怎么将一个连续的xml字符串格式化输出
// a demo string
string xml = "<Root><Eles><Ele>abc</Ele><Ele>123</Ele></Eles></Root>";
System.Xml.XmlDocument doc = new System.Xml ......
1. 打开新的窗口并传送参数：
传送参数：
response.write("＜script＞window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)＜/script＞")
接收参数：
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
2.为按钮添加对话框
Button1 ......
public sealed class DbOper
{
///<summary>
/// DbOper类的构造函数
///</summary>
private DbOper()
{
}
......
