Question

string vehicleno="kl-12-22222";
DateTime dt = DateTime.Now;
string location = "Trivandrum";

我有一个来自数据库的字符串 string s =＆＃34; （车号）在{Location Name}的{Time}偏离了GeoFence。＆＃34;;

我该如何展示

kl-12-11111 has deviated from GeoFence at 12/29/2014 in Trivandrum

在C＃中

？

Answer 1

将字符串输出放入您想要显示它的输出方法中（不知道您是控制台应用程序还是winforms或其他任何东西）

string output = String.Format(  "{0} has deviated from GeoFence at {1} in {2}",vehicleno,dt.ToString(),location )

Answer 2

您可以使用String.Format方法，例如

int vehicleNumber = 123;
DateTime time = DateTime.Now;
string locationName = "here";
string text = string.Format("{0} has deviated from GeoFence at {1} in {2}", vehicleNumber.ToString(), time.ToString("mm/dd/yyyy"), locationName);

Answer 3

如果您可以为模板使用不同的字符串，则可以使用以下内容：

string formattedText = string.Format(
    "{0} has deviated from GeoFence at {1} in {2}", 
    vehicleno, 
    dt.ToString("MM/dd/yyyy"), 
    location);

或者，您可以使用模板将Replace（）调用链接在一起：

string formattedText = s.Replace("{Vehicle No}", vehicleno).Replace(...).Replace(...);
