Question

我有一个很长的字符串，我想把变量放入，但我不能

string body = @"-----------------------------13254316446590
Content-Disposition: form-data; name=""max_file_size""

100000
-----------------------------13254316446590
Content-Disposition: form-data; name=""uploadedfile""; filename=""file.txt""
Content-Type: application/octet-stream

<!>C:\Users\anton\AppData\Local\Temp\lost\file.txt<!>
-----------------------------13254316446590--
";

我想制作路径和文件名变量我知道这看起来像一个愚蠢的问题，但我试图把“”+“”没有成功

Answer 1

您是否尝试过使用String.Format(...)？ http://msdn.microsoft.com/en-us/library/system.string.format%28v=vs.110%29.aspx

示例：

DateTime dat = new DateTime(2012, 1, 17, 9, 30, 0); 
string city = "Chicago";
int temp = -16;
string output = String.Format("At {0} in {1}, the temperature was {2} degrees.",
                              dat, city, temp);
Console.WriteLine(output);
// The example displays the following output: 
//    At 1/17/2012 9:30:00 AM in Chicago, the temperature was -16 degrees.

尝试String.Format()

String.Format("some string {0} other string {1}", path, filename);
