如何解决这笔款项。 1 + 2 = 12不是3.这是我的代码vb

Private Sub btnHitung_Click（sender as Object，e As EventArgs）处理btnHitung 。点击 txtJumlahB.Text =（txtStokSisa.Text + txtBarangM.Text）结束子

谢谢 我尝试过： i try sum来自谷歌搜索。但我找不到相同的错误。

解决方案

TextBox始终返回字符串，从不返回整数。字符串1与整数不一样，1。 您将两个字符串连接在一起，1+2= 12。 您必须将字符串转换为整数才能将它们组合在一起。查看 Integer.TryParse（） [ ^ ]来实现这一目标。

How can i fix that sum. 1+2 = 12 not 3. This my code vb

Private Sub btnHitung_Click(sender As Object, e As EventArgs) Handles btnHitung.Click txtJumlahB.Text = (txtStokSisa.Text + txtBarangM.Text) End Sub

thanks before What I have tried: i try sum from google search. but i can't find the same wrong with this.

解决方案

TextBox's always return strings, never integers. A string, "1", is not the same as an integer, 1. You're concatenating two strings together, "1" + "2" = "12". You have to convert the string to integers in order to add them together. Look into Integer.TryParse()[^] to accomplish that.
