Visual Basic字符串执行

Question

插入倒逗号（“”）转换为字符串的Visual Basic

Dim str As String 

str = "*.doc" & "," & "*.docx" 

我想文本框中显示"*.doc" & "," & "*.docx"

Answer 1

它根本不清楚你在问什么。如果你这样做，结果字符串将是*.doc,*.docx。如果你想倒逗号（引号），你会做这样的事情：

str = Chr$(34) & "*.doc" & Chr$(34) & "," & Chr$(34) & "*.docx" & Chr$(34) 

这将产生类似

"*.doc","*.docx" 

这是你在找什么？如果没有，让我们知道你想要完成什么，我们可以帮助你。

Answer 2

写入字符串，只要你想它代表：

str = "*.doc" & "," & "*.docx" 

双引号逃脱他们：

str = ""*.doc"" & "","" & ""*.docx"" 

然后引用串整：

str = """*.doc"" & "","" & ""*.docx""" 

?str 
"*.doc" & "," & "*.docx" 

Answer 3

我测试了这个与一个消息框，它为我工作得很好。

Dim str As String = "*.doc" & "," & "*.docx" 
textbox1.text = str 

Answer 4

这对我有用，试试吧。

Dim str As String = """ * .doc"" & "","" & ""*.docx """ 
TextBox1.Text = str 

Answer 5

VB6代码：

Dim str As String 
str = "*.doc" & "," & "*.docx" 
Text1.Text = str 

VB.net代码：

Dim str As String 
str = "*.doc" & "," & "*.docx" 
TextBox1.Text = str 

这两项工作。
