如何在C＃中的特定位置替换字符串？

Question

    string q1 = "What [replace string] years? ";

In the above question I want to replace "years of study" with `model.values` 
so my required output should be as:

    string q1 = "What [replace string] years?";

其中“ 2013,2014”将来自数据库。

因此，我需要将值附加到静态问题，这些值将来自使用mvc模型的数据库。

我如何在特定位置替换字符串，我在那儿有任何建议，它将对我有所帮助。

Answer 1

使用string.Format（）

将您的q1声明更改为此

string q1 = "What type of legal entity was the Company during the {0} tax years? ";

然后格式化字符串

var q2 = string.Format(q1, <replacement  string>);

其中<replacement string>是您要替换的值

所以，

var q2 = string.Format(q1, model.Values);

请参阅MSDN上的文档

Answer 2

您可以使用$ c＃6.0功能

$"What type of legal entity was the Company during the {Model.values} tax years? "

Answer 3

尝试这样：-

  string q2=  String.Format("What type of legal entity was the Company during the {0} tax years? ", YourModelName.Years);

Answer 4

您可以尝试使用string.Replace

string q1 = "What type of legal entity was the Company during the [years of the study] tax years? ";
q1 = q1.Replace("[years of the study]", someValue.ToString());

但是，这不是一个很好的做法。 如其他建议那样，使用string.Format更好。
