Question

我有一个案文箱,我作为投入输入。

"Two; abc@kk.com;"

string[] result = txt_to.Text.Split( ; );

so what happens here is the result takes three strings. 1. two 2. abc@kk.com 3. "" (empty space) since there is a ; after the email it considers that as a string how can I discard the 3rd string that it takes. It happens when I enter the email and a semicolon and press the space bar it throws a error. If it is just space after the semicolon the split should discard it how to do that

Answer 1

I m gathering you want to split the string into a number of strings, but exclude any "empty" strings (those consisting only of whitespace)? This ought to help you out...

string[] result = txt_to.Text.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);

Answer 2

var arr = mystring.Split(new string[]{";"}, StringSplitOptions.RemoveEmptyEntries);

Answer 3

String SplitOptions 参数

var result = yourString.Split(new string[] {";"}, StringSplitOptions.RemoveEmptyEntries);

Answer 4

采用同样的方法,添加<条码> 规范使用。

Answer 5

我认为,不仅在最后,从结果中排除空洞是明智的。如果情况如此,你可以使用

char[] separators = new char[]{ ; };
string[] result = txt_to.Text.Split(separators , StringSplitOptions.RemoveEmptyEntries);

Answer 6

string s=txt_to.Text;
s = s.Replace(" ", "");
string[] result = s.Split( ; );
