动态的类型转换

TypeConvert,TypeDescriptor

 

 

public static void DynamicConvert<T>(object source,out T target) { //string转换为任意类型 if(source is string) { TypeConverter tc = TypeDescriptor.GetConverter(typeof(T)); object temp = tc.ConvertFromInvariantString(source.ToString()); target = (T)temp; } //任意类型转换为string else if(!(source is string) && (typeof(T) == typeof(string))) { TypeConverter tc = TypeDescriptor.GetConverter(typeof(T)); if(tc.CanConvertTo(typeof(string))) target = (T)(object)tc.ConvertToInvariantString(source.ToString()); else target = (T)(object)source.ToString(); } //如果source是队列 else if(source is ArrayList && typeof(T).IsArray) { ArrayList list = (ArrayList)source; Type elementType = typeof(T).GetElementType(); Array arr = Array.CreateInstance(elementType,list.Count); TypeConverter tc = TypeDescriptor.GetConverter(elementType); for(int i=0;i<list.Count;i++) { arr.SetValue(tc.ConvertFromInvariantString(list[i].ToString()),i); } target = (T)(object)arr; } else target = (T)(object)(string.Empty); }
