C#Arcengine打开一个GDB中的表

要使用C# ArcEngine打开一个GDB中的表,可以按照以下步骤进行操作:
1. 创建一个工作空间工厂对象,指定GDB所在的路径
```
IWorkspaceFactory workspaceFactory = new FileGDBWorkspaceFactory();
IWorkspace workspace = workspaceFactory.OpenFromFile(gdbPath, 0);
```
2. 从工作空间中获取表格对象
```
IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace;
ITable table = featureWorkspace.OpenTable(tableName);
```
其中,`tableName`为要打开的表名。
通过以上两步,就可以在C# ArcEngine中打开一个GDB中的表了。

C#Arcengine打开GDB中指定名的图层
你可以使用C# ArcEngine中的以下代码打开GDB中指定名称的图层:
```csharp
//打开工作空间
IWorkspaceFactory workspaceFactory = new FileGDBWorkspaceFactory();
IWorkspace workspace = workspaceFactory.OpenFromFile("C:\\data\\myGDB.gdb", 0);
//打开要素数据集
IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace;
IFeatureDataset featureDataset = featureWorkspace.OpenFeatureDataset("myFeatureDataset");
//打开要素类
IFeatureClass featureClass = featureDataset.OpenFeatureClass("myFeatureClass");
```
其中,`"C:\\data\\myGDB.gdb"` 是你的GDB文件路径,`"myFeatureDataset"` 是你的要素数据集名称,`"myFeatureClass"` 是你要打开的图层名称。你可以根据自己的实际情况修改这些参数。
C#Arcengine在GDB数据库中复制一个表
您好!要在C#ArcEngine中复制一个表,需要使用Geoprocessing工具中的CopyFeatures工具。以下是示例代码:
```csharp
//获取源表格
IFeatureClass sourceFC = ((IFeatureWorkspace)sourceWorkspace).OpenFeatureClass(sourceTableName);
//获取目标工作空间
IFeatureWorkspace targetWorkspace = (IFeatureWorkspace)targetWorkspace;
//设置复制参数
IWorkspaceName sourceWorkspaceName = ((IDataset)sourceWorkspace).FullName as IWorkspaceName;
IWorkspace sourceParent = ((IWorkspaceFactory)sourceWorkspaceName.WorkspaceFactory).OpenFromFile(sourceWorkspaceName.PathName, 0);
IDataset sourceDataset = sourceParent.OpenFeatureClass(sourceTableName) as IDataset;
IName sourceName = sourceDataset.FullName;
IDataset targetDataset = targetWorkspace.OpenFeatureClass(targetTableName) as IDataset;
IName targetName = targetDataset.FullName;
Geoprocessor gp = new Geoprocessor();
CopyFeatures copyFeatures = new CopyFeatures();
copyFeatures.in_features = sourceName;
copyFeatures.out_feature_class = targetName;
//执行复制操作
gp.Execute(copyFeatures, null);
```
其中,sourceWorkspace是源表格所在的工作空间,sourceTableName是源表格的名称,targetWorkspace是目标工作空间,targetTableName是目标表格的名称。执行该代码后,指定的源表格将会被复制到目标工作空间中,并命名为目标表格的名称。
