SuperMap8C C#二次开发，创建矢量数据集、字段

基于SuperMap8C二次开发，C#语言，创建点、线、面等数据集、字段

public void CreateDataSetTest()
{
DatasourceConnectionInfo datasourceConnectinfo = new DatasourceConnectionInfo();
datasourceConnectinfo.EngineType = EngineType.SQLPlus;//数据库类型，SqlServer
datasourceConnectinfo.Server = "127.0.0.1";//服务器名称
datasourceConnectinfo.Database = "TestData";// 数据库名称
datasourceConnectinfo.Alias = "TestData";//数据库别名
datasourceConnectinfo.User = "sa"; //数据库用户;
datasourceConnectinfo.Password = "123456";//数据库密码;
datasourceConnectinfo.Driver = "SQL Server";//数据库驱动

//打开地图的工作空间
Workspace mWorkspace = SuperMap.Desktop.Application.ActiveApplication.Workspace;
string strWorkSpaceName = System.Windows.Forms.Application.StartupPath + @"\Data\数据.smwu";
WorkspaceConnectionInfo connectinfo = new WorkspaceConnectionInfo(strWorkSpaceName);
mWorkspace.Open(connectinfo);

//打开连接
Datasource datasource = mWorkspace.Datasources.Open(datasourceConnectinfo);

//创建矢量数据集
DatasetVectorInfo datasetTest = new DatasetVectorInfo();// 设置矢量数据集的信息
datasetTest.Type = DatasetType.Region;//数据集类型（点、线、面、属性等）
datasetTest.IsFileCache = true;
datasetTest.Name = "测试面数据集";//数据集名称
datasource.Datasets.Create(datasetTest);// 创建矢量数据集

//创建字段
DatasetVector dataset_TestRegion = (DatasetVector)SimpleWorkSpace.m_workspace.Datasources[DBSwmConn.m_Alias].Datasets[Model.DataSetName.XJXZQ];
FieldInfos Region_fieldInfos = dataset_TestRegion.FieldInfos;

FieldInfo field_ID = new FieldInfo("ID", FieldType.Int32); //标识
field_ID.Caption = "标识";//字段别名
field_ID.IsRequired = true;//是否为必填字段 如果字段为必填字段则为true，否则为false，默认值为false。

FieldInfo field_User = new FieldInfo("Ueser", FieldType.Text);
field_User.Caption = "用户";
field_User.IsRequired = false;

FieldInfo field_Remark = new FieldInfo("Remark", FieldType.Text);//备注
field_Remark.Caption = "备注";
field_Remark.DefaultValue = "备注信息";//默认值

//将字段添加
Region_fieldInfos.Add(field_ID);
Region_fieldInfos.Add(field_User);
Region_fieldInfos.Add(field_Remark);
}
