如何使用泛型？

本文介绍了如何使用泛型？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

大家好， 在下面的示例中，我想用泛型替换int。在 订单字中，我想用float，double，byte或 替换int。我试图找到一个通用的界面或 这样的东西，但我没找到。 public static int MaxSum（int [来源） { int maxSoFar = 0，maxEndingHere = 0; for（int i = 0; i< source.Length ; i ++） { maxEndingHere = Math.Max（maxEndingHere + source [i]， 0）; maxSoFar = Math.Max（maxSoFar，maxEndingHere）; } 返回maxSoFar; } 想用公共静态替换此方法签名T $ / $ MaxSum< T>（T [] source）其中T：I ???。谢谢你的帮助。 马丁

Hi all, In the following example, I''d like to replace int by a generic. In order word, I would like to replace int by float, double, byte or something like that. I''ve tried to find a common interface or something like that, but I didn''t find. public static int MaxSum(int[] source) { int maxSoFar = 0, maxEndingHere = 0; for (int i = 0; i < source.Length; i++) { maxEndingHere = Math.Max(maxEndingHere + source[i], 0); maxSoFar = Math.Max(maxSoFar, maxEndingHere); } return maxSoFar; } In would like to replace this method signature by public static T MaxSum<T>(T[] source) where T : I???. Thank you for your help. Martin

也不会在即将推出的版本中，AFAIK ... 你知道这种功能是否被考虑用于未来......？b $ b？ - http：// www。 markrae

Nor in the forthcoming version, AFAIK... Would you know if this sort of functionality is even being considered for the future...? -- www.markrae

嗨John和Mark， 谢谢你的回答。所以，如果我理解得很好，我必须切割并使用不同的签名来粘贴这个方法吗？ - public static int MaxSum（int [] source） - public static float MaxSum（float [] source） - public static double MaxSum（double [] source） - etc. 马丁 Hi John and Mark, Thank you for you answer. So, if I understand well, I have to cut and paste this method with different signature? - public static int MaxSum(int[] source) - public static float MaxSum(float[] source) - public static double MaxSum(double[] source) - etc. Martin
