C#,StringToEnum,我能把它变成一个通用函数吗

试试这个:

public static T StringToEnum<T>(String value)
{
     return (T)Enum.Parse(typeof(T), value, true);
}

public static T StringToEnum<T>(String value)
{
    return (T) Enum.Parse(typeof(T),value,true) ;
}

下面是我使用的方法扩展。

/// <summary>
/// Will parse and string value and return the Enum given.  Case is ignored when doing the parse.
/// </summary>
/// <param name="typeOfEnum">The type of the Enum to Parse</param>
/// <param name="value">The string value for the result of the Enum</param>
/// <param name="errorValue">If an error is encountered this value is returned.  (For example could be an Enum)</param>
/// <returns>Returns Enum Object</returns>
public static T ToEnum<T>(this string value)
{
    return (T)Enum.Parse(typeof(T), value, true);
}
