[英]Replacing multiple words in a string sentence C#
Hello guys, I don't need the answer but I would look to know and find out what I'm doing wrong.大家好,我不需要答案,但我想知道并找出我做错了什么。 As a beginner I got a very "easy" assignment in my studies.作为初学者,我在学习中得到了一项非常“简单”的作业。 I need to create a string and inside this string I need to replace some words by other words without using the for loop as so: ( also I want to print it but I got no clue where to put Console.WriteLine and google searching for 1 hour didn't work or asking a colleage.我需要创建一个字符串,在这个字符串中,我需要用其他单词替换一些单词而不使用 for 循环:(我也想打印它,但我不知道把 Console.WriteLine 放在哪里,谷歌搜索 1小时没有工作或问大学。
/* Excersice: use with stringbuilder * cat becomes littlecat * dog becomes littledog * mouse becomes littlemouse * words the must be replace by a * do not use a loop*/ /* 练习:与 stringbuilder 一起使用 * cat 变成 littlecat * dog 变成 littledog * 鼠标变成 littlemouse * 必须用 a 替换的单词 * 不要使用循环 */

Error CS5001: Program does not contain a static "Main" method suitable for an entry point ( I don't get this doesn't almost any program starts with this static Main args? )错误 CS5001:程序不包含适合入口点的静态“Main”方法(我不明白几乎没有任何程序以这个静态 Main args 开始?)
Error CS8112: replacethisstring(string)' is a local function and must therefore always have a body.错误 CS8112:replacethisstring(string)' 是一个本地函数,因此必须始终有一个主体。 ( I just gave it a body right? I opened the { and close it } and put a replace with return. ) (我只是给了它一个主体,对吗?我打开 { 并关闭它 } 并用 return 替换。)
The method declaration ends with ;
方法声明以;
结尾;
that's the reason for CS8112这就是CS8112的原因
The Main method has to return void
(or 'int' )you've modified it to string
, that's the reason for CS5001 Main 方法必须返回void
(或 'int' )您已将其修改为string
,这就是CS5001的原因
If you want the program to print the output on the console use:如果您希望程序在控制台上打印输出,请使用:
using System;
....
Console.WriteLine(output)
;
你不能有;
at the end of a function declaration that has a body to it.在具有主体的函数声明的末尾。namespace Opgavens_leerpad_3_oefening
{
class Program
{
public static void Main(string[] args)
{
StringBuilder sb = new StringBuilder();
sb.Append("Can the cat find the mouse without waking the dog.");
sb = replacethisstring(sb);
Console.WriteLine(sb.ToString());
Console.ReadLine(); // To Stop the Console from closing.
static StringBuilder replacethisstring(StringBuilder dogCat)
{
dogCat = dogCat.Replace("cat", "littlecat");
dogCat = dogCat.Replace("dog", "littldog");
dogCat = dogCat.Replace("mouse", "littlemouse");
dogCat = dogCat.Replace("the", "a");
return dogCat;
}
}
}
}
You can place the function within the Main or outside.您可以将函数放置在 Main 内或外部。 Normally you would find functions outside of the Main class.通常,您会在 Main 类之外找到函数。
public static void Main(string[] args)
{
...
}
public static string replacethisstring(string dogCat)
{
...
}
Having several issues like typos, syntax error etc. Additionally, the excercise having a condition that needs to use with stringbuilder.有几个问题,如拼写错误、语法错误等。此外,该练习有一个需要与 stringbuilder 一起使用的条件。
So, try this.所以,试试这个。
static void Main(string[] args)
{
StringBuilder sb = new StringBuilder("Can the cat find the mouse without waking the dog?");
sb = replacethisstring(sb);
Console.WriteLine(sb.ToString());
Console.ReadLine();
}
static StringBuilder replacethisstring(StringBuilder dogCat)
{
StringBuilder hondKat = dogCat.Replace("cat", "littlecat");
hondKat = dogCat.Replace("the", "a");
hondKat = dogCat.Replace("dog", "littledog");
hondKat = dogCat.Replace("mouse", "littlemouse");
return hondKat;
}
