Example introduction to processing newline characters in json_javascript skills

json is a commonly used data type in ajax and is often used. But what to do if a newline character appears in the field?

It is obviously inappropriate to remove it. Some fields already have line breaks, how can I remove them?

Tested the processing of json class and found nothing. Unexpectedly, the final processing is really so simple:

The background code replaces the newline character rn with \n, the character received by the front-end code js is n

Copy code The code is as follows:

public static string ConvertFromListTojson(IList{
string[] cols = columnInfos.Split(new char[]{','},StringSplitOptions.RemoveEmptyEntries);
StringBuilder sb = new StringBuilder(300);
sb.Append("{"total":");
sb.Append(total);
sb.Append(","rows":");
sb.Append("[");
foreach (T t in list)
{
sb.Append("{");
foreach (string col in cols)
{
string name = ""{0}":"{1}",";
string value = getValue(t, col);
value = value.Replace("rn", "\r\n");
sb.Append(string.Format(name, col, value));
}
if (cols.Length > 0)
{
int length = sb.Length;
sb.Remove(length - 1, 1);
}
sb.Append("},");
}
if (list.Count > 0)
{
int length2 = sb.Length;
sb.Remove(length2 - 1, 1);
}

sb.Append("]") ;
sb.Append("}");
return sb.ToString();
}
private static string getValue(T t, string pname) where T : class
{
Type type = t.GetType();
PropertyInfo pinfo = type.GetProperty(pname);
if (pinfo != null)
{
object v = pinfo.GetValue (t, null);
return v != null ? v.ToString() : "";
}
else
{
throw new Exception("Attribute does not exist" pname) ;
}

}
