谁帮我看看有关TreeView编写的一段递归程序.

Question

you got an infinite loop there, try to change
InitTree(Nds[Nds.Count-1].Nodes,intId);
===>
InitTree(tmpNd.Nodes,tmpNd.ID);

Answer 1

这是我的初始化方法：
private void IntiTree(DataSet objDataSet,TreeNodeCollection Nds,
String ParentID,String ParentField,String NameField,String NodeIDField)
{
DataView dv=new DataView() ; TreeNode tmpNd;
String strId;
dv.Table = objDataSet.Tables[0]; if (ParentID=="null")
dv.RowFilter=ParentField+ " is null";
else
dv.RowFilter=ParentField + "='"+ParentID+"'"; foreach(DataRowView objRow in dv)
{
tmpNd=new TreeNode();
//if (objRow[NodeIDField]!=null)
strId=Convert.ToString((Guid) objRow[NodeIDField]);
//strId=NodeIDField;
tmpNd.Tag=strId.ToString();
tmpNd.Text=objRow[NameField].ToString();
Nds.Add(tmpNd);
IntiTree(objDataSet,Nds[Nds.Count-1].Nodes,strId,ParentField,NameField,NodeIDField);               
}            }
这是我的表字段：WerehouseClassID,WerehouseClassCode, WerehouseClassName,WerehouseClassParentID,WerehouseClassLevel
