在C#VS2012中写入文件

本文关键字：文件 C#VS2012 | 更新日期: 2023-09-27 18:29:15

我正在使用以下代码写入项目根文件夹中的文件。。

public class Service2 : IService2
{
    public Boolean SaveInfo(String firstName, String lastName, DateTime dateOfBirth,
    String email, String streetAddress, String suburb, String state, int postcode,
    Job job)
    {
        string text = firstName + " " + lastName + " " + dateOfBirth + " " + email + " " + streetAddress + " " + suburb + " " + state + " " + postcode + " " + job;
        String[] people = Regex.Split(text, " ");
        using (System.IO.StreamWriter file = new System.IO.StreamWriter("Person.txt", true))
        {
            foreach (string c in people)
            {
            file.Write(c);
            file.Close();
            return true;
            }
            return false;
        }
    }

基本上，它返回一个布尔值，这取决于文件是否被写入。。。我很难真正找到写入文件的内容。它在执行时确实返回true-我在WCF测试仪中运行WCF服务，并用值调用它以写入文件。。。然而，当我从右侧的解决方案资源管理器打开Person.txt文件时，没有任何内容被写入其中…

所以我的问题是，这是将文本行写入文本文件的最佳方式吗？如果是，我哪里出了问题？

在C#VS2012中写入文件

尝试使用此代码

string text = firstName + " " + lastName + " " + dateOfBirth + " " + email + " " + streetAddress + " " + suburb + " " + state + " " + postcode + " " + job;
        String[] people = text.Split(" ");
if (!File.Exists("Person.txt"))
        {
            // Create a file to write to. 
            File.WriteAllLines(path, people , Encoding.UTF8);
        }
else
 File.AppendAllText("Person.Text", people , Encoding.UTF8);

    public Boolean SaveInfo(String firstName, String lastName, DateTime dateOfBirth,
String email, String streetAddress, String suburb, String state, int postcode)
    {
        string text = firstName + " " + lastName + " " + dateOfBirth + " " + email + " " + streetAddress + " " + suburb + " " + state + " " + postcode + " ";
        String[] people = Regex.Split(text, " ");
        try
        {
            using (System.IO.StreamWriter file = new System.IO.StreamWriter("Person.txt", true))
            {
                foreach (string c in people)
                {
                    file.Write(c);
                }
                file.Close();
            }
            return true;
        }
        catch (Exception)
        {
            return  false;
        }
    }

您在数组中的第一个字符串之后关闭文件，但必须在循环遍历数组中的每个字符串之后关闭它。对我来说，它正在工作，但我们可能需要看到您的函数调用

尝试这个

public Boolean SaveInfo(String firstName, String lastName, DateTime dateOfBirth,
    String email, String streetAddress, String suburb, String state, int postcode,
    Job job)
    {
     try{
            string text = firstName + "'r'n" + lastName + "'r'n" + dateOfBirth + "'r'n" + email + "'r'n" + streetAddress + "'r'n" + suburb + "'r'n" + state + "'r'n" + postcode + "'r'n" + job;
            using (System.IO.StreamWriter file = new System.IO.StreamWriter("Person.txt"))
           {
               file.WriteLine(text );
               file.Close();
               return true;   
           }
       }
       catch(Exception ex)
       {
           return false;
       }
    }

一种老式的

    using (FileStream fs = File.Create(yourFilePath)) 
    {
        byte[] info = new UTF8Encoding(true).GetBytes(text);
        fs.Write(info, 0, info.Length);
    }
