C# 怎么将PropertyGrid控件中输入内容加密?(PropertyGrid控件的内容是读一个自定义类中的属性,属性内容可以改变)
找到了在属性上面设置 [PasswordPropertyText(true)]
设置为 private 属性
/// <summary>
///
/// </summary>
public class Editor : UITypeEditor
{
/// <summary>
/// 更改属性值编辑样式(增加省略号按钮)
/// </summary>
/// <param name="context"></param>
/// <returns></returns>
public override UITypeEditorEditStyle GetEditStyle(System.ComponentModel.ITypeDescriptorContext context)
{
return UITypeEditorEditStyle.Modal;
}
/// <summary>
/// 增加自定义用户控件
/// </summary>
/// <param name="context"></param>
/// <param name="provider"></param>
/// <param name="value"></param>
/// <returns></returns>
public override object EditValue(System.ComponentModel.ITypeDescriptorContext context, System.IServiceProvider provider, object value)
{
var formES = provider.GetService(typeof(IWindowsFormsEditorService)) as IWindowsFormsEditorService;
if (formES != null)
{
var popedControl = new PropertyGridMoreControl(value);
//弹出窗口
//formES.ShowDialog(窗口/对话框);
//下拉框
formES.DropDownControl(popedControl);
}
return base.EditValue(context, provider, value);
}
}
要在C#中使用propertyGrid控件时将内容加密,可以采取以下步骤:
public class EncryptedStringConverter : TypeConverter
{
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
{
return destinationType == typeof(string);
}
public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
{
// 将属性值转换为加密的字符串
string encryptedValue = Encrypt((string)value);
return encryptedValue;
}
public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
{
return sourceType == typeof(string);
}
public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
{
// 将加密的字符串解密为原来的属性值
string encryptedValue = (string)value;
string decryptedValue = Decrypt(encryptedValue);
return decryptedValue;
}
// 编写加密方法和解密方法
private string Encrypt(string value)
{
// 加密逻辑
}
private string Decrypt(string encryptedValue)
{
// 解密逻辑
}
}
public class Student
{
private string name = "Tom";
[TypeConverter(typeof(EncryptedStringConverter))]
public string Name
{
get { return name; }
set { name = value; }
}
// 其他属性...
}
这样,当在propertyGrid控件中编辑该属性时,属性值会自动加密和解密。
希望以上解决方案对你有帮助!如果还有其他问题,请随时提问。
