我正在尝试将表单中五个文本框的内容添加到名为“TextBox1”的多行文本框中。但是,每次我更改文本框的内容时,它不会添加另一行内容,而是替换预先存在的行。如何打印下一行。
Dim Newline As String
Newline = System.Environment.NewLine
TextBox1.Text = "Plane Truss"
TextBox1.Text = TextBox1.Text & Newline & "JointCoordinates"
TextBox1.AppendText(Newline & Joint# & " " & coordinates1 & " " & bc1 & " " & jointloads1 & " " & settlements1 & " " & jointrotation1)
