做的新闻发布系统中需要用到这个,上网找了一下,在CSDN处找到个方法,蛮好的,记下来了。。嘿嘿。。
/// <summary> /// 将指定字符串按指定长度进行剪切, /// </summary> /// <param name= "oldStr "> 需要截断的字符串 </param> /// <param name= "maxLength "> 字符串的最大长度 </param> /// <param name= "endWith "> 超过长度的后缀 </param> /// <returns> 如果超过长度,返回截断后的新字符串加上后缀,否则,返回原字符串 </returns> public static string StringTruncat(string oldStr, int maxLength, string endWith) { if (string.IsNullOrEmpty(oldStr)) // throw new NullReferenceException( "原字符串不能为空 "); return oldStr + endWith; if (maxLength < 1) throw new Exception("返回的字符串长度必须大于[0] "); if (oldStr.Length > maxLength) { string strTmp = oldStr.Substring(0, maxLength); if (string.IsNullOrEmpty(endWith)) return strTmp; else return strTmp + endWith; } return oldStr; }
