The final text file will always be a blank line, and more consult how to solve?

CodePudding user response:

 
Appendline lines end with a newline, append not 
Sb. AppendLine (item. The ToString ()); 
Sb. Append (item. The ToString ()); 

CodePudding user response:

Append Line you require Line ah,

CodePudding user response:

refer to the second floor is nu month god reply:

Append Line are you require a newline,

reference 1/f, kill matt, bull response:

 
Appendline lines end with a newline, append not 
Sb. AppendLine (item. The ToString ()); 
Sb. Append (item. The ToString ()); 

I don't understand, sb. Append (" content "); ,
This sentence is not start a new line should be written to two words?
But the effect is written to start a new line after the "content" two characters

CodePudding user response:

 sw. Write (sb. ToString (). TrimEnd (new char [] {\ 'r', '\ n'})); 

Perfect solution, two teachers ~ ~, thank you

CodePudding user response:

AppendLine is an extra line breaks after
Append just add

 
StringBuilder sb=new StringBuilder(); 
Sb. Append (" 123 "); 
Sb. AppendLine (" 456 "); 
Sb. Append (" 789 "); 

Results:
123456
789

Logical error:

 sb. Append ($" first line "); 

Foreach (Mapping item in MapData) 
{
Sb. AppendLine (); 
Sb. Append (item. The ToString ()); 
} 

CodePudding user response:

refer to 6th floor interacting in a professional developer response:

logic error:

 sb. Append ($" first line "); 

Foreach (Mapping item in MapData) 
{
Sb. AppendLine (); 
Sb. Append (item. The ToString ()); 
} 

See your code, the feeling is good simple ah
My mind is to what, all of this thought...

CodePudding user response:

If you can see what you said on the # 3 floor logic with you write their own code does not "unity" will be better,
