Question

我试图在Visual Basic中使用file.WriteLine将一串代码插入到文本文件中，但每当我检查文本文件时，它只复制了字符串名称，而不是它的内容，这是我的代码：

文本文件将包含＆＃34; printf（strc011）;＆＃34;而不是替换＆＃34; strc011＆＃34;部分与＃34; Hello World！＆＃34;

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim file As System.IO.StreamWriter
        file = My.Computer.FileSystem.OpenTextFileWriter("TEST.txt", True)
        Dim strc011 As String
        strc011 = "Hello World!"
        file.WriteLine("#include<stdio.h>
                        main()
                        {
                        printf(strc011);}
        ")
        file.Close()
    End Sub
End Class

Answer 1

假设您正在使用VB 14 or newer，那么您将要使用String Interpolation，这是一种模板。

这是一个正确的实施：

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim file As System.IO.StreamWriter
        file = My.Computer.FileSystem.OpenTextFileWriter("TEST.txt", True)
        Dim strc011 As String
        strc011 = "Hello World!"
        file.WriteLine($"#include<stdio.h>
                        main()
                        {
                        printf({strc011});}
        ")
        file.Close()
    End Sub
End Class

我弄清楚了，结果我定义了＆amp;以错误的方式调用字符串，这是工作代码：

Public Class Form1 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim file As System.IO.StreamWriter file = My.Computer.FileSystem.OpenTextFileWriter("TEST.txt", True) Dim strc011 As String = "Hello World!" file.WriteLine("#include<stdio.h> main() { printf(""" & strc011 & """);} ") file.Close() End Sub End Class

Dim strc011 As String =＆＃34; Hello World！＆＃34; - 用于定义字符串

＆＃34;＆＃34;＆＃34; ＆安培; strc011＆amp; ＆＃34;＆＃34;＆＃34; - 用于调用
