常用擴展方法

1 C#擴展方法

1.1 刪除指定字符串

1.1.1 代碼實現(xiàn)

`/// <summary>/// 刪除指定字符串/// </summary> public static string RemoveString(this string @this, string removeStr) {// 查找被刪除的字符串的位置int num = @this.IndexOf(removeStr);// 1 被刪除的字符串不存在if (num == -1)return @this;// 2 被刪除的字符串在開頭if (num == 0)return @this.Substring(removeStr.Length);// 3 被刪除的字符串在末尾if (@this.Length == removeStr.Length + num)return @this.Substring(0, num);// 4 被刪除的字符串在中間return @this.Substring(0, num) + @this.Substring(num + removeStr.Length); }`

1.1.2 刪除所有字符串擴展

`/// <summary> /// 刪除所有指定字符串 /// </summary> public static string RemoveAllString(this string @this, string removeAllStr) {string removeStr = RemoveString(@this, removeAllStr);// 查找有沒有刪除完所有的字符串if (removeStr.IndexOf(removeAllStr) == -1)return removeStr;return RemoveAllString(removeStr, removeAllStr); }`

1.2 比較所有字符串

/// <summary> /// 比較所有字符串 /// </summary> public static bool EqualsAny(this string @this, StringComparison comparisonType, params string[] values) {return values.Any(v => @this.Equals(v, comparisonType)); }/// <summary> /// https://docs.microsoft.com/zh-cn/dotnet/api/system.stringcomparison?redirectedfrom=MSDN&view=netframework-4.7.2 /// </summary> public static bool EqualsAny(this string @this, params string[] values) {return EqualsAny(@this, StringComparison.CurrentCulture, values); }

1.3 確定字符串是否包含任何提供的值

/// <summary> /// 確定字符串是否包含任何提供的值 /// </summary> public static bool ContainsAny(this string @this, params string[] values) {return @this.ContainsAny(StringComparison.CurrentCulture, values); }/// <summary> /// 確定字符串是否包含任何提供的值 /// </summary> public static bool ContainsAny(this string @this, StringComparison comparisonType, params string[] values) {return values.Any(v => @this.IndexOf(v, comparisonType) > -1);}

1.4 隨機數(shù)擴展

`public static class RandomExtensions{/// <summary> /// 隨機獲取項 /// </summary> public static T GetRandItem<T>(this T[] source) {T[] list = ShuffleSort(source);System.Random rnd = NewRandom();int index = rnd.Next(0, list.Length);return list[index]; }/// <summary> /// 隨機獲取字符串中的字符 /// </summary> public static char GetRandItem(this string source) {char[] list = source.ToCharArray();return GetRandItem<char>(list);}/// <summary> /// 隨機返回一個0 - 1的數(shù) /// </summary> public static double GetRandItemInRangeDouble() {System.Random random = NewRandom(); return random.NextDouble(); }/// <summary> /// 洗牌算法隨機排序 /// </summary> public static T[] ShuffleSort<T>(T[] source) {System.Random random = NewRandom();int var;T temp;int len = source.Length;for (int i = 0; i < len; ++i){var = random.Next(0, len);temp = source[i];source[i] = source[var];source[var] = temp;}return source; }/// <summary> /// 隨機數(shù)種子 /// </summary> private static int GetRandomSeed() {byte[] bytes = new byte[4];System.Security.Cryptography.RNGCryptoServiceProvider rng = new System.Security.Cryptography.RNGCryptoServiceProvider();rng.GetBytes(bytes);return BitConverter.ToInt32(bytes, 0); }private static System.Random NewRandom() {return new System.Random(GetRandomSeed()); }}`

2 unity方法擴展

2.1 Vector3擴展

`public static class Vector3Extensions{public static Vector3 CalculateMedian(this Vector3 @vector3, Vector3 other) {return new Vector3(vector3.x + other.x, vector3.y + other.y, vector3.z + other.z) * 0.5f; }public static Vector3 SetX(this Vector3 @vector3, float x) {return new Vector3(x, vector3.y, vector3.z); }public static Vector3 SetY(this Vector3 @vector3, float y) {return new Vector3(vector3.x, y, vector3.z); }public static Vector3 SetZ(this Vector3 @vector3, float z) {return new Vector3(vector3.x, vector3.y, z); }}`

2.2 Transform擴展

`public static class TransformExtensions{public static void SetX(this Transform @transform, float x) {@transform.position = new Vector3(x, @transform.position.y, @transform.position.z); }public static void SetY(this Transform @transform, float y) {@transform.position = new Vector3(@transform.position.x, y, @transform.position.z); }public static void SetZ(this Transform @transform, float z) {@transform.position = new Vector3(@transform.position.x, @transform.position.y, z); }public static void RestartTransform(this Transform @transform) {@transform.position = Vector3.zero;@transform.localRotation = Quaternion.identity;@transform.localScale = Vector3.one; }public static void ResetChildTransform(this Transform @transform, bool recursive = false) {foreach (Transform child in transform){child.RestartTransform();if (recursive){child.ResetChildTransform(recursive);}} }public static void AddChildrens(this Transform @transform, params GameObject[] childrens) {Array.ForEach(childrens, child => child.transform.parent = transform); }public static T Position<T>(this T @this, Vector3 position) where T : Component {@this.transform.position = position;return @this; }public static T LocalScale<T>(this T @this, Vector3 localPosition) where T : Component {@this.transform.localPosition = localPosition;return @this; }public static T LocalScale<T>(this T @this, float size) where T : Component {@this.transform.localPosition = Vector3.one * size;return @this; }public static T Rotation<T>(this T @this, Quaternion rotation) where T : Component {@this.transform.rotation = rotation;return @this; }public static T LocalRotation<T>(this T @this, Quaternion localRotation) where T : Component {@this.transform.localRotation = localRotation;return @this; }public static T[] GetComponentsInRealChildren<T>(this GameObject @this, bool isGrandsonObj = false) {T[] childrens = @this.GetComponentsInChildren<T>(isGrandsonObj);List<T> list = new List<T>(childrens);list.RemoveAt(0);return list.ToArray(); }public static T[] GetComponentsInRealChildren<T>(this Transform @this, bool isGrandsonObj = false) {T[] childrens = @this.GetComponentsInChildren<T>(isGrandsonObj);List<T> list = new List<T>(childrens);list.RemoveAt(0);return list.ToArray(); }public static Transform[] GetRealChildren(this Transform @this) {List<Transform> list = new List<Transform>();foreach(Transform child in @this){list.Add(child);}return list.ToArray(); }public static GameObject[] GetRealChildren(this GameObject @this) {List<GameObject> list = new List<GameObject>();foreach (Transform child in @this.transform){list.Add(child.gameObject);}return list.ToArray(); }public static GameObject[] ConvertGameObjects(this Transform[] @this) {int len = @this.Length;GameObject[] objs = new GameObject[len];for(int i = 0; i < len; i++){objs[i] = @this[i].gameObject;}return objs; }}`
