.net通用类型转换方法
标签:net lob class change tco size using 目标 get
由于数据类型多,要按照逐个类型写一个类型转换的方法的话一是代码量多,显得累赘。
using System;
using System.ComponentModel;
using System.Globalization;
///
/// 类型转换
///
/// 要转换的值
/// 转换的目标类型
///
public static object To(object value, Type destinationType)
{
return To(value, destinationType, CultureInfo.InvariantCulture);
}
///
/// 类型转换
///
/// 要转换的值
/// 转换的目标类型
/// 区域信息
///
public static object To(object value, Type destinationType, CultureInfo culture)
{
if (value != null)
{
var sourceType = value.GetType();
var destinationConverter = TypeDescriptor.GetConverter(destinationType);
if (destinationConverter != null && destinationConverter.CanConvertFrom(value.GetType()))
return destinationConverter.ConvertFrom(null, culture, value);
var sourceConverter = TypeDescriptor.GetConverter(sourceType);
if (sourceConverter != null && sourceConverter.CanConvertTo(destinationType))
return sourceConverter.ConvertTo(null, culture, value, destinationType);
if (destinationType.IsEnum && value is int)
return Enum.ToObject(destinationType, (int)value);
if (!destinationType.IsInstanceOfType(value))
return Convert.ChangeType(value, destinationType, culture);
}
return value;
}
///
/// 类型转换
///
/// 目标类型
/// 要转换的值
///
public static T To(object value)
{
return (T)To(value, typeof(T));
}
