C#+Ae实现CreateFeatureClass() 方法的代码

下面是使用ArcObjects的C#代码实现CreateFeatureClass()方法：

using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.Geometry;

public void CreateFeatureClass(string workspacePath, string featureClassName, esriGeometryType geometryType)
{
    //打开工作空间
    IWorkspaceFactory workspaceFactory = new ShapefileWorkspaceFactory();
    IWorkspace workspace = workspaceFactory.OpenFromFile(workspacePath, 0);
    IFeatureWorkspace featureWorkspace = workspace as IFeatureWorkspace;

    //设置字段集
    IFields fields = new Fields();
    IFieldsEdit fieldsEdit = fields as IFieldsEdit;
    fieldsEdit.AddField(CreateField("ID", esriFieldType.esriFieldTypeOID));
    fieldsEdit.AddField(CreateField("Name", esriFieldType.esriFieldTypeString));

    //创建要素类
    IFeatureClass featureClass = featureWorkspace.CreateFeatureClass(featureClassName, fields, null, null, geometryType, "Shape", "");
}

private IField CreateField(string name, esriFieldType fieldType)
{
    IField field = new Field();
    IFieldEdit fieldEdit = field as IFieldEdit;
    fieldEdit.Name_2 = name;
    fieldEdit.Type_2 = fieldType;
    return field;
}

其中，`workspacePath`为工作空间路径，`featureClassName`为要素类名称，`geometryType`为几何类型。此方法将在指定工作空间中创建一个名为`featureClassName`的要素类，并添加两个字段“ID”和“Name”。
