如何在vb.net中计算文本文件中的列数并显示在文本框中？

Dim filePath As String = "文件路径"
Dim reader As New StreamReader(filePath)

Dim line As String = reader.ReadLine()

Dim columns As Integer = line.Split("分隔符").Length

textBox.Text = columns.ToString()

Dim filePath As String = "文件路径"
Dim reader As New StreamReader(filePath)

Dim line As String = reader.ReadLine()
Dim columns As Integer = line.Split("分隔符").Length

textBox.Text = columns.ToString()

reader.Close()
