如何在c＃中的特定位置替換字符串？

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」將來自數據庫。

所以我需要附加值到靜態問題，值將來自數據庫使用mvc模型。

如何在一個特定的位置替換字符串我堅持有任何建議它會幫助我提前感謝。

Answer 1

使用的String.format（）

改變你Q1聲明此

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

然後格式化字符串

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

與<replacement string>是值你代

所以，

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

見documentation MSDN上

Answer 2

你可以用$ C＃6.0的功能

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

Answer 3

嘗試這樣的： -

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

Answer 4

您可以嘗試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，這不是一個很好的做法。使用string.Format，正如其他人所建議的那樣更好。
