Question

我将c＃应用程序表单与文本文件连接起来。但我不希望它被硬编码。到目前为止，我在文件中的代码如下所示。我不想显示文件名和路径文件。我宁愿让它放入app.config文件并从app.config filw中使用它。你能告诉我在这个文件和app.config文件中我要做哪些更改：

  private void button1_Click(object sender, EventArgs e)
    {

    string sqlConnectionString = @"C:\Jaspreet_Files\LoadOrgInPortal.txt";

        var fileContents = System.IO.File.ReadAllText(@"C:\Jaspreet_Files\LoadOrgInPortal.txt");


        fileContents = fileContents.Replace("{param_1}", textBox1.Text.ToString());
        fileContents = fileContents.Replace("{param_2}", textBox2.Text.ToString());
        fileContents = fileContents.Replace("{param_3}", textBox3.Text.ToString());
        fileContents = fileContents.Replace("{param_4}", textBox4.Text.ToString());
        System.IO.File.WriteAllText(@"C:\Jaspreet_Files\NewLoadOrgInPortal.txt", fileContents);

        Application.Exit();

    }

我的app.config文件目前是空的。我的意思是我还没有做任何编码。

Answer 1

应用程序设置非常简单。

将您的属性添加到App.Config应用设置中，例如

  <appSettings>
    <add key="sqlConnectionString" value="C:\Jaspreet_Files\LoadOrgInPortal.txt" />
  </appSettings>

..并阅读它们，例如

   var sqlConnectionString = System.Configuration.ConfigurationSettings.AppSettings["sqlConnectionString"];

using System;
using System.Collections.Specialized;
using System.Configuration;
...
...
...

private void button1_Click(object sender, EventArgs e)
{
    AppSettingsReader reader = new AppSettingsReader();
    string txtFilePath  = (string)reader.GetValue("txtFilePath", typeof(string));

    //string sqlConnectionString = @"C:\Jaspreet_Files\LoadOrgInPortal.txt";
    string sqlConnectionString = txtFilePath;

    //var fileContents = System.IO.File.ReadAllText(@"C:\Jaspreet_Files\LoadOrgInPortal.txt");
    var fileContents = System.IO.File.ReadAllText(txtFilePath);


    fileContents = fileContents.Replace("{param_1}", textBox1.Text.ToString());
    fileContents = fileContents.Replace("{param_2}", textBox2.Text.ToString());
    fileContents = fileContents.Replace("{param_3}", textBox3.Text.ToString());
    fileContents = fileContents.Replace("{param_4}", textBox4.Text.ToString());
    System.IO.File.WriteAllText(@"C:\Jaspreet_Files\NewLoadOrgInPortal.txt", fileContents);

    Application.Exit();

}

使用app.config文件将c＃应用程序表单连接到文本文件
