本文介绍了两种使用C#创建PictureMarkerSymbol的方法。第一种方法通过ArcGIS Server API操作图片文件并设置为标记符号；第二种方法则利用WPF中的BitmapImage实现图片显示。

今天写代码时遇到要用后台C#代码定义一个PictureMarkerSymbol，以前只用XAML写过，不会，遂找来谷哥，百度到帖子如下，后来又通过微软的MSDN找到另一个方法，现列在下面，留存作为备忘查询帖。

Message	I had spent long time for finding sample code that can show me how to create a PictureMarkerSymbol in ArcGIS server with C#. However, I couldn't find it. Now, I figured out how to do it. Here I would like to share my code with you. 1) add following two namespaces: using System.Drawing; using System.Drawing.Imaging; 2) create a System.Drawing.Image object: System.Drawing.Image symbolImage = System.Drawing.Image.FromFile("D://yourimagefilepathandname.bmp"); 3) create PictureMarkerSymbol. ESRI.ArcGIS.ADF.ArcGISServer.PictureMarkerSymbol pms = new ESRI.ArcGIS.ADF.ArcGISServer.PictureMarkerSymbol(); pms.Picture = ESRI.ArcGIS.ADF.ArcGISServer.Converter.ToByteArray(symbolImage, System.Drawing.Imaging.ImageFormat.Bmp); pms.Size = 20.0; Happy coding :) FEI 方法二：（http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.bitmapsource.aspx） // Create the image element. Image simpleImage = new Image(); simpleImage.Width = 200; simpleImage.Margin = new Thickness(5); // Create source. BitmapImage bi = new BitmapImage(); // BitmapImage.UriSource must be in a BeginInit/EndInit block. bi.BeginInit(); bi.UriSource = new Uri(@"/sampleImages/cherries_larger.jpg",UriKind.RelativeOrAbsolute); bi.EndInit(); // Set the image source. simpleImage.Source = bi;
