SaveLayoutToStream. Error: Could not find part of the path "c: \ TreeListLayout \"

Question

我试着运行举个例子-link
用户 - 管理员
场景：
- 我展开树列表节点；
- 我执行 "SaveLayoutToStream_mtd ()" 方法；

我排队

System.IO.FileStream outFile = new System.IO.FileStream(fileName, System.IO.FileMode.Create);

一个错误

System.IO.DirectoryNotFoundException: "Could not find part of the path" c: \ TreeListLayout \ "."

所有代码

string fileName = @"c:\TreeListLayout\";
public void SaveLayoutToStream_mtd()
{            
    System.IO.FileStream outFile = new System.IO.FileStream(fileName, System.IO.FileMode.Create);
    treeList1.SaveLayoutToStream(outFile);
    outFile.Close();
}

如何修复错误？

Answer 1

您是否看到您的代码与您引用的示例之间的区别？您正在尝试写入具有无效名称 c:\TreeListLayout\ 的文件 - 那是一个目录名称。删除尾部斜杠或附加文件名
