C＃首字母大写字母 - 更有效的方法？

Question

我有一些代码可以完成我想要它做的事情，但我想知道是否有更快的方法来做我想要的事情。

用户将输入他们的名字，我想确保他们的名字尽可能接近这种格式：

• john＆gt;约翰
• julie＆gt;朱莉

我的代码：

// First Name
s_in_GetUserFirstName = s_in_GetUserFirstName.ToLower();
c_in_UserFirstNameFirstChar = s_in_GetUserFirstName[0];
s_in_UserFirstNameFirstChar = c_in_UserFirstNameFirstChar.ToString().ToUpper();
s_in_GetUserFirstName = s_in_GetUserFirstName.Remove(0, 1);
s_in_GetUserFirstName = s_in_UserFirstNameFirstChar + s_in_GetUserFirstName;
// Last Name
s_in_GetUserLastName = s_in_GetUserLastName.ToLower();
c_in_UserLastNameFirstChar = s_in_GetUserLastName[0];
s_in_UserLastNameFirstChar = c_in_UserLastNameFirstChar.ToString().ToUpper();
s_in_GetUserLastName = s_in_GetUserLastName.Remove(0, 1);
s_in_GetUserLastName = s_in_UserLastNameFirstChar + s_in_GetUserLastName;

我所做的是将字符串分成两部分，第一部分和其余部分。我将第一个字符大写并从字符串中删除该字符。然后我将字符串合并为一个。

您可以在一行中执行此操作

test.Substring(0,1).ToUpper()+test.Substring(1);

或者像Rob在评论中所建议的那样这样做
