要将文本框中的数据显示到TreeView上,您需要编写一些代码来实现以下步骤:
1. 获取文本框中的数据
2. 将数据拆分为所需的节点和子节点
3. 创建TreeView节点和子节点
4. 将节点和子节点添加到TreeView中
以下是一个示例代码,可以帮助您开始:
C#代码:
private void btnAddToTree_Click(object sender, EventArgs e)
{
//获取文本框中的数据
string data = txtInput.Text;
//拆分数据为节点和子节点
string[] nodes = data.Split(';');
//创建TreeView节点和子节点
foreach (string node in nodes)
{
string[] subNodes = node.Split(',');
if (subNodes.Length > 1)
{
//创建带有子节点的节点
TreeNode parent = new TreeNode(subNodes[0]);
for (int i = 1; i < subNodes.Length; i++)
{
TreeNode child = new TreeNode(subNodes[i]);
parent.Nodes.Add(child);
}
//将节点添加到TreeView中
treeView1.Nodes.Add(parent);
}
else
{
//创建不带子节点的节点
TreeNode child = new TreeNode(subNodes[0]);
//将节点添加到TreeView中
treeView1.Nodes.Add(child);
}
}
}
VB.NET代码:
Private Sub btnAddToTree_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddToTree.Click
'获取文本框中的数据
Dim data As String = txtInput.Text
'拆分数据为节点和子节点
Dim nodes As String() = data.Split(";"c)
'创建TreeView节点和子节点
For Each node As String In nodes
Dim subNodes As String() = node.Split(","c)
If subNodes.Length > 1 Then
'创建带有子节点的节点
Dim parent As New TreeNode(subNodes(0))
For i As Integer = 1 To subNodes.Length - 1
Dim child As New TreeNode(subNodes(i))
parent.Nodes.Add(child)
Next
'将节点添加到TreeView中
treeView1.Nodes.Add(parent)
Else
'创建不带子节点的节点
Dim child As New TreeNode(subNodes(0))
'将节点添加到TreeView中
treeView1.Nodes.Add(child)
End If
Next
End Sub
