错误    1    非静态字段、方法或属性“SuperMap.Data.WorkspaceConnectionInfo.Type.get”要求对象引用    D:\SuperMap\project\WindowsFormsApplication1\WindowsFormsApplication1\Form1.cs    41    13    WindowsFormsApplication1
错误    2    非静态字段、方法或属性“SuperMap.Data.WorkspaceConnectionInfo.Server.get”要求对象引用    D:\SuperMap\project\WindowsFormsApplication1\WindowsFormsApplication1\Form1.cs    42    13    WindowsFormsApplication1
 

Answer 1

WorkspaceConnectionInfo.Type = WorkspaceType.SMWU;

WorkspaceConnectionInfo.Server = @"D:\SuperMap\supermap-iobjectsdotnet-10.1.1-19230-84288-all\SampleData\World\World,smwu";

您在对工作空间连接信息赋值的这两行代码错误。

您对工作空间连接信息变量实例化名称是workspaceConnectionInfo，而不是WorkspaceConnectionInfo。

将其修改为即可。（大小写W→w）
