c# - How can i add a space/empty line between the first and second lines in single string variable? -

string tables = this.webbrowser1.document.getelementbyid("tblproducts").innertext;             using (stringreader reader = new stringreader(tables))             {                 string line;                 while ((line = reader.readline()) != null)                 {                     // line                 }             } 

this did now:

string tables = this.webbrowser1.document.getelementbyid("tblproducts").innertext;             streamwriter w = new streamwriter(@"c:\temp\table1.txt");             w.writeline(tables);             w.close();              string[] lines = file.readalllines(@"c:\temp\table1.txt");             (int = 0; < lines.length; i++)             {                 lines[i] = lines[i].insert(0, "here added text");             } 

but instead insert iwant somehow add new line between line number 1 , line number 2. if lines contain 31 lines in end should contain 32 lines new line between line 1 , line 2. not add new line end between 1 , 2.

i think you're saying that, given text looks this:

this line 1 second line here , third line 

what want is:

this line 1 <empty line here> second line here , third line 

if so, should pretty easy do:

string tables = this.webbrowser1.document.getelementbyid("tblproducts").innertext; var lines = tables.split(new[]{environment.newline}, stringsplitoptions.none).tolist(); lines.insert(1, ""); string newtext = string.join(environment.newline, lines);
