c# - Split a string by a character

Question

I have this string here:

String FileNameOrginal = "lighthouse-126.jpg";

and I am trying to split the string into 2, seperating it with "-"

I have tried the following, but I get a syntax error on the Spilt:

String FileNameOrginal = drProduct["productHTML"].ToString();
string[] strDataArray = FileNameOrginal.Split("-");

Please Help, I do not understand what I am doing wrong.

Answer 1

你只需要一个字符而不是字符串：

string[] strDataArray = FileNameOrginal.Split('-');

Answer 2

所以问题是您需要一个输入数组，如下所示：

string[] strDataArray = FileNameOrginal.Split(
    new string[] { "-" },
    StringSplitOptions.None);

Answer 3

  string FileNameOrginal = "lighthouse-126.jpg";
        string file1 = FileNameOrginal.Split('-')[0];
        string file2 = FileNameOrginal.Split('-')[1];

Answer 4

代替：

string[] strDataArray = FileNameOrginal.Split("-");

尝试

string[] strDataArray = FileNameOrginal.Split('-');
