WPF中如何写入配置文件ini

在WPF中读写config配置文件，很简单。

1. 在你的工程中，添加app.config文件。文件的内容绝如默认为：

[csharp] view plain copy

<中裤?xml version="1.0" encoding="utf-8" ?>

<configuration>

</configuration>

2.如果你想给程序配置一些参数，就在<configuration>标签中添加<appSettings>.例如：

[html] view plain copy

<?xml version="1.0"卖宏简 encoding="utf-8" ?>

<configuration>

<appSettings>

<add key="Path" value="SFSFSDSDS"/>

<add key="NAME" value="FUCk"/>

</appSettings>

</configuration>

3.然后你在程序里需要的地方读写它就可以了。先引用

[csharp] view plain copy

using System.Configuration

4.读：

[csharp] view plain copy

string str = ConfigurationManager.AppSettings["Path"]

5.写：

[csharp] view plain copy

Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)

cfa.AppSettings.Settings["NAME"].Value = "WANGLICHAO"

cfa.Save()

6.收工！

private void CheckBox_是否保存为文本文件_Checked(object sender, RoutedEventArgs e)

{

string fileName = string.Empty

if (string.IsNullOrEmpty(this.TextBox_文件位置.Text))

{

var dialog = new SaveFileDialog { DefaultExt = "txt"旁燃, AddExtension = true, FileName = DateTime.Now.ToString("yyyyMMdd_HHmmss", DateTimeFormatInfo.CurrentInfo) + "发票" }

if (dialog.ShowDialog() != System.Windows.Forms.DialogResult.OK)

{

System.Windows.MessageBox.Show("请选择要保存的文运败虚件枯腔名称")

return

}

fileName = dialog.FileName

}

else

{

fileName = TextBox_文件位置.Text

}

using (var writer = new StreamWriter(fileName, false, Encoding.UTF8))

{

writer.Write(TextBox_发票.Text)

}

}

private void Button_选择_Click(object sender, RoutedEventArgs e)

{

ClearText()

var dialog = new OpenFileDialog { Multiselect = false, Filter = "TxtFiles|*.txt" }

if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)

{

this.TextBox_文件位置.Text = dialog.FileName

using (var stream = new StreamReader(dialog.FileName, Encoding.Default))

{

TextBox_发票.Text = stream.ReadToEnd()

}

}

}
