功能：远程web上传shp文件，然后添加到指定的SDE已经存在的FeatureClass里
思路：读取shp里的Feature，编程连接到SDE，打开指定的FeatureClass，然后插入。
缺点：现在只能适用没有注册为版本的FeatureClass，在测试过程中，如果注册为版本，则运行报“Objects in this class cannot be updated outside an edit session ” 这个错误，一直不知道怎么解决，还请高手指点。
主要实现代码：
文件上传功能实现：
private void UpLoadFiles()
string filepath = Server.MapPath("./") + "UpLoadFiles";
HttpFileCollection uploadedFiles = Request.F
for (int i = 0; i & uploadedFiles.C i++)
HttpPostedFile userPostedFile = uploadedFiles[i];
if (userPostedFile.ContentLength & 0)
userPostedFile.SaveAs(filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName));
message.Text = this.ShpFile + "上传成功！";
message.Text = this.ShpFile + "上传失败！";
读取shp里的Feature功能实现：
public IFeatureClass GetShpFeatureClass()
IFeatureClass returnFeatureClass =
//取得服务中的基本信息
IServerContext soc = GetSoc();
string filepath = Server.MapPath("./") + "UpLoadFiles";
IWorkspaceFactory pWorkspaceFactory = (IWorkspaceFactory)soc.CreateObject("esriDataSourcesFile.ShapefileWorkspaceFactory");
IFeatureWorkspace pFeatWS = pWorkspaceFactory.OpenFromFile(@filepath, 0) as IFeatureW
//IFeatureLayer pLayer = (IFeatureLayer)pSOC.CreateObject("esriCarto.FeatureLayer");
returnFeatureClass = pFeatWS.OpenFeatureClass("china-hlj.shp");
//pLayer.Name = "rivers";
soc.ReleaseContext();
return returnFeatureC
添加Feature到SDE的功能实现：
public void Add_Fea(string FeaName, IFeature insertFeature)
IServerContext soc = GetSoc();
IPropertySet propSet = new PropertySetClass();
propSet.SetProperty("SERVER", this.SdeServer);
propSet.SetProperty("INSTANCE", this.SdeInstance);
propSet.SetProperty("USER", this.SdeUser);
propSet.SetProperty("PASSWORD", this.SdePassword);
propSet.SetProperty("VERSION", this.SdeVerson);
IWorkspaceFactory pWorkSpFac = (IWorkspaceFactory)soc.CreateObject("esriDataSourcesGDB.SDEWorkspaceFactory");
IFeatureWorkspace pFeaWorkSp =
pFeaWorkSp = (IFeatureWorkspace)(pWorkSpFac.Open(propSet, 0));//打开要素空间
IFeatureClass FeaCls = pFeaWorkSp.OpenFeatureClass(FeaName);//取得要素集
IFeatureCursor FeaCursor = FeaCls.Insert(true);
IFeatureBuffer FeaBuffer = FeaCls.CreateFeatureBuffer(); ;
IField Fld = new FieldClass();
IFields Flds = insertFeature.F
for (int i = 0; i & Flds.FieldC i++)
Fld = Flds.get_Field(i);
int index = FeaBuffer.Fields.FindField(Fld.Name);
if (index != -1)
FeaBuffer.set_Value(index, insertFeature.get_Value(i));
FeaCursor.InsertFeature(FeaBuffer);
soc.ReleaseContext();
pFeaWorkSp =
使用注意事项：在使用时要设置SdeServer、SdeInstance、SdeUser、SdePassword、SdeVerson、FeatureClass等属性。
