树视图子节点错误 [英] Tree View child nodes error

问题描述

当我在c＃中使用以下代码时，它会给出错误

When i use the following code in c# it gives error

parent.ChildNodes.Add(child);
nParent.PopulateOnDemand = true;

错误15'System.Windows.Forms.TreeNode'不包含'ChildNodes'的定义，没有扩展方法'ChildNodes'接受类型为'System.Windows.Forms.TreeNode'的第一个参数'（你是否缺少using指令或汇编引用？）

错误3'System.Windows.Forms.TreeNode'不包含'PopulateOnDemand'的定义，并且没有扩展方法'PopulateOnDemand'接受类型为'System.Windows.Forms.TreeNode'的第一个参数'可能是发现（你错过了使用指令或汇编参考吗？）



帮我........ .....

Error 15 'System.Windows.Forms.TreeNode' does not contain a definition for 'ChildNodes' and no extension method 'ChildNodes' accepting a first argument of type 'System.Windows.Forms.TreeNode' could be found (are you missing a using directive or an assembly reference?)
Error 3 'System.Windows.Forms.TreeNode' does not contain a definition for 'PopulateOnDemand' and no extension method 'PopulateOnDemand' accepting a first argument of type 'System.Windows.Forms.TreeNode' could be found (are you missing a using directive or an assembly reference?)

Help Me.............

推荐答案

尝试：

Try:

parent.Nodes.Add(child);

根据MSDN，该属性被称为节点 [ ^ ]而不是ClildNodes



http://msdn.microsoft.com/en-us/library/system.windows.forms.treenode.aspx [ ^ ]

According to MSDN, the property is called Nodes [^]and not ClildNodes
