抓换字符串问题

[ronaltn]

string strTime = "7:00"
我现在想把这个字符串转换成"700"，请问怎么转换？

[wt_sanlian]

string strTime = "7:00";
string newTime = strTime.Remove(1,1)

[hhc123]

string strTime = "7:00";
Console.WriteLine( strTime.Remove(strTime.IndexOf(':'),1));

[风之影子]

string strTime = "7:00";
string newTime = strTime.Replace(":","");

[liherun]

string strTime = "7:00";
 strTime = strTime.Remove(strTime.IndexOf(':'),1);
