feature class上传sde数据库

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。

效果图：



主要实现代码：

文件上传功能实现：

C#代码
private void UpLoadFiles()  
    {  
        string filepath = Server.MapPath("./") + "UpLoadFiles";  
 
        HttpFileCollection uploadedFiles = Request.Files;  
        for (int i = 0; i < uploadedFiles.Count; i++)  
        {  
            HttpPostedFile userPostedFile = uploadedFiles[i];  
            try 
            {  
                if (userPostedFile.ContentLength > 0)  
                {  
                    userPostedFile.SaveAs(filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName));                      
                }  
                message.Text = this.ShpFile + "上传成功！";  
            }  
            catch 
            {  
                message.Text = this.ShpFile + "上传失败！";  
            }  
        }  
    } 

private void UpLoadFiles()
    {
        string filepath = Server.MapPath("./") + "UpLoadFiles";

        HttpFileCollection uploadedFiles = Request.Files;
        for (int i = 0; i < uploadedFiles.Count; i++)
        {
            HttpPostedFile userPostedFile = uploadedFiles[i];
            try
            {
                if (userPostedFile.ContentLength > 0)
                {
                    userPostedFile.SaveAs(filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName));                   
                }
                message.Text = this.ShpFile + "上传成功！";
            }
            catch
            {
                message.Text = this.ShpFile + "上传失败！";
            }
        }
    }

读取shp里的Feature功能实现：

C#代码
public IFeatureClass GetShpFeatureClass()  
    {  
        IFeatureClass returnFeatureClass = null;  
        //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 IFeatureWorkspace;  
        //IFeatureLayer pLayer = (IFeatureLayer)pSOC.CreateObject("esriCarto.FeatureLayer");  
        returnFeatureClass = pFeatWS.OpenFeatureClass("china-hlj.shp");  
        //pLayer.Name = "rivers";  
        soc.ReleaseContext();  
        return returnFeatureClass;  
    } 

public IFeatureClass GetShpFeatureClass()
    {
        IFeatureClass returnFeatureClass = null;
        //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 IFeatureWorkspace;
        //IFeatureLayer pLayer = (IFeatureLayer)pSOC.CreateObject("esriCarto.FeatureLayer");
        returnFeatureClass = pFeatWS.OpenFeatureClass("china-hlj.shp");
        //pLayer.Name = "rivers";
        soc.ReleaseContext();
        return returnFeatureClass;
    }添加Feature到SDE的功能实现：

C#代码
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 = null;  
        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.Fields;  
        for (int i = 0; i < Flds.FieldCount; 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 = null;  
 
    }
