如何从C＃中的数据库中获得\\的双引号值

Question

I am fetching some string value from the database which should have double quotes, for example:

"DoubleQuotes"

but when ever it comes to the c# part above string value becomes:

\"DoubleQuotes\"

I have even tried using replace method but it takes out the \\ but also removes " from everywhere.

Code:

repository = new Repository();
string genericTemplate = Convert.ToString(@repository.GetTemplateWithoutFormulas(sheetName)); // this returns the string value from the db
return genericTemplate;

O/p on the browser I get is:

"{\"version\":\"9.40.20153.0\",\"sheetCount\":2,\"sheets\":{\"Sheet1\":{\"name\":\"Sheet1\",\"selections\":{\"0\":{\"row\":1,\"rowCount\":1,\"col\":1,\"colCount\":1}},\"rowCount\":200,\"columnCount\":20,\"activeRow\":1,\"activeCol\":1,\"theme\":\"Office\",\"rowHeaderData\":{\"defaultDataNode\":{\"style\":{\"themeFont\":\"Body\"}}},\"colHeaderData\":{\"defaultDataNode\":{\"style\":{\"themeFont\":\"Body\"}}},\"data\":{\"dataTable\":{\"0\":{\"0\":{\"value\":\"daman\",\"style\":{\"autoFormatter\":{\"customerCultureName\":\"en-US\"}}},\"1\":{\"value\":\"sandhu\",\"style\":{\"autoFormatter\":{\"customerCultureName\":\"en-US\"}}}},\"1\":{\"0\":{\"value\":\"hello\",\"style\":{\"autoFormatter\":{\"customerCultureName\":\"en-US\"}}},\"1\":{\"value\":\"chu\",\"style\":{\"autoFormatter\":{\"customerCultureName\":\"en-US\"}}}}},\"defaultDataNode\":{\"style\":{\"themeFont\":\"Body\"}}},\"index\":0},\"Sheet2\":{\"name\":\"Sheet2\",\"selections\":{\"0\":{\"row\":0,\"rowCount\":1,\"col\":0,\"colCount\":1}},\"rowCount\":200,\"columnCount\":20,\"activeRow\":0,\"activeCol\":0,\"theme\":\"Office\",\"index\":1}}}"

Your GetTemplateWithoutFormulas() method doesn't just return a string, it returns a JSON string of a JSON object. Apparently you stringified one too many times. You need to parse out that JSON string and get the string representation of that result.

I don't know what libraries you're using but assuming Json.NET, you could do something like this:

var template = repository.GetTemplateWithoutFormulas(sheetName);
var token = JToken.Parse(template);
return token.ToString();

You should also consider making that method return a JSON object instead, rather than a JSON string of a JSON object. Then you wouldn't have to do this in the first place.
