我會去像這樣的東西,特別是如果您的控件列表可能會延後更長時間:
private void button1_Click(object sender, EventArgs e)
{
Form1.WriteToFile(textBox1, textBox2, textBox3, checkBox);
}
private static void WriteToFile(params Control[] controls)
{
string accountsSettingsFile = Path.GetDirectoryName(Application.LocalUserAppDataPath)
+ "\\accounts" + "\\accounts.txt";
List<string> lines = new List<string>(controls.Length);
foreach (var control in controls)
{
string value = Form1.GetValueFromControl(control);
//this will skip null entries, not sure you really
//want to do that, otherwise when you read this file back in
//you will have no idea which values represent which fields
if (value != null)
lines.Add(value);
}
//This will overwrite the file.
//If you want to append use File.AppendAllLines
File.WriteAllLines(accountsSettingsFile, lines);
}
private static string GetValueFromControl(Control control)
{
if (control is TextBox)
{
return ((TextBox)control).Text;
}
if (control is CheckBox)
{
return ((CheckBox)control).Checked.ToString();
}
return null;
}
雖然,因爲您正在使用此設置,所以將原始值寫入文本文件是一種非常脆弱的方法。我可以推薦使用序列化?雖然這需要你在你的項目中引用Newtonsoft.Json(通過的NuGet):
private void Button_Write_Click(object sender, EventArgs e)
{
AccountSettings settings = new AccountSettings();
settings.Setting1 = this.textBox1.Text;
settings.Setting2 = this.textBox2.Text;
settings.Setting3 = this.textBox3.Text;
settings.CheckboxValue = this.checkBox.Checked;
WriteJson(settings, SettingsFile);
}
private void Button_Read_Click(object sender, EventArgs e)
{
AccountSettings settings = ReadJson<AccountSettings>(SettingsFile);
this.textBox1.Text = settings.Setting1;
this.textBox2.Text = settings.Setting2;
this.textBox3.Text = settings.Setting3;
this.checkBox.Checked = settings.CheckboxValue;
}
private static string SettingsFile
{
get
{
return Path.GetDirectoryName(Application.LocalUserAppDataPath)
+ "\\accounts" + "\\accounts.txt";
}
}
private static void WriteJson(Object obj, string path)
{
var ser = new JsonSerializer();
using (var file = File.CreateText(path))
using (var writer = new JsonTextWriter(file))
{
ser.Serialize(writer, obj);
}
}
private static T ReadJson<T>(string path)
where T: new()
{
if (!File.Exists(path))
return new T();
var ser = new JsonSerializer();
using (var file = File.OpenText(path))
using (var reader = new JsonTextReader(file))
{
return ser.Deserialize<T>(reader);
}
}
private class AccountSettings
{
public string Setting1 { get; set; }
public string Setting2 { get; set; }
public string Setting3 { get; set; }
public bool CheckboxValue { get; set; }
}
}
這給你一個強類型可以寫入和讀取一個非常具體和可重複的方式AccountSettings
對象。
