ArcEngine临时数据存储 创建内存工作空间

参考网址，这里

工作中有时候需要使用临时数据，以前都是创建一个默认的shapefile或者gdb，今天发现esri官方帮助文档给出了一个方法，可以创建内存工作空间，代码如下：

public static IWorkspace CreateInMemoryWorkspace()
{// Create an in-memory workspace factory.Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.InMemoryWorkspaceFactory");IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);// Create an in-memory workspace.IWorkspaceName workspaceName = workspaceFactory.Create("", "MyWorkspace",null, 0);// Cast for IName and open a reference to the in-memory workspace through the name object.IName name = (IName)workspaceName;IWorkspace workspace = (IWorkspace)name.Open();return workspace;
}
