如何控制在DataGrid中不能输入全角数字,符号,字母？ =============================================== 1.屏蔽全角 2.把全角转为半角 private string ToDBS(string str)//全角转半角 { return Regex.Replace(str,"[\\w]",new MatchEvaluator(RegReplace)); } private string RegReplace(Match m) { if((int)m.Value[0]>=65281&(int)m.Value[0]<=65374)return ((char)((int)m.Value[0]-65248)).ToString(); if((int)m.Value[0]==12288)return ((char)32).ToString();; return m.Value; } Top
