我想在代码字中显示公司名称，例如Dell Computers = DC，但在连接字符串时出错。

在foreach循环之外定义NewID。您无法同时定义和分配变量。
string str = txtCompanyname.Text.Trim();
string[] output = str.Split(' ');
string newid= string.empty;
foreach (string s in output)
{
// Console.Write(s[0] + " ");
Response.Write(s[0]);
newid += s[0].ToString();//getting error here
}
答案 1 :(得分：0)
string str = txtCompanyname.Text.Trim();
string[] output = str.Split(' ');
foreach (string s in output)
{
Response.Write(s);
string newid += s;
}

你可以使用linq。
只需拆分全名并选择每个部分的第一个字符;
string str = "Dell Computers";
var abbr = new string(str.Split(new[] {' '}, StringSplitOptions.RemoveEmptyEntries)
.Select(x => char.ToUpper(x[0]))
.ToArray());
答案 3 :(得分：0)
您可以使用LINQ执行此操作：
public string FirstLetters(string s)
{
return String.Join("", s.Trim().Split(' ').Select(w => w.Substring(0, 1).ToUpper()));
}
var result = FirstLetter(txtCompanyname.Text);
此代码执行以下操作：
