怎么把两字段相加

[wojiao_xiaoqiang]

string strremark = TextBox13.Text.Trim();
string strremark_2 = TextBox14.Text.Trim();
我想要的是string str= 前面这么两个字段相加起来
例如第一个字段string strremark=我来了
第二个字段string strremark_2=真的么
那么 string str=我来了，真的么

我不会写 string str= 这 怎么写呢

[修改一下昵称]

直接用 “+” 操作

string str2 = "aa";
string str3 = "bb";
string str1 = str2 + str3;

[丰云]

string str= strremark + ", " + strremark_2;

[yufenghua]

+ ....

参考：

string strremark = TextBox13.Text.Trim();
string strremark_2 = TextBox14.Text.Trim();
string str=strremark +","+strremark;

[Taiyangchen]

string strremark = TextBox13.Text.Trim();
  string strremark_2 = TextBox14.Text.Trim();
string str = strremark +strremark_2 ;

就是字符串相加而已

string str=string strremark + string strremark_2

[T_long]

string strremark = TextBox13.Text.Trim();
string strremark_2 = TextBox14.Text.Trim();
string str=(strremark +","+strremark).tosString();

这样才是

[skyqingtian]

string strremark = TextBox13.Text.Trim();
  string strremark_2 = TextBox14.Text.Trim();
string str=strremark.ToString() +","+strremark_2.ToString();

[wanghuaide]

[Pro_ah]

       string strremark = TextBox13.Text.Trim();
       string strremark_2 = TextBox14.Text.Trim();
       string str = strremark + "," + strremark_2;
      或   
      string strremark = TextBox13.Text.Trim();
      string strremark_2 = TextBox14.Text.Trim();
      string str = strremark .ToString ()+ "," + strremark_2.ToString ();
