can't merge two string!

Question

3.00/5 (1 vote)

See more:

In my latest C# application which reads a byte stream from a serial communication device to a byte array, after the reading operation I store it into a string variable

before storing it I call the below function to convert it to string

C++

System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
return enc.GetString(input);

but the resulted two string can't be merged

C#

string resultString = string1 + string2;

I also check both combination

C#

string resultString = string2 + string1;

then only string2 content stores in the resultString

no exception occurred during merging , the resulted string always shows the content in the first string

I think the ending character may cause the problem?

Solution 1

Not sure how you are "merging" the strings, but it should be as easy as:

C#

string resultString = string1 + string2;

Solution 2

In all likelihood, your second string isn't correct. Check your second string to make sure it is correct before you combine the two srings.

Solution 4

I think we're probably missing some of the story. Try this to see what you get:

C#

string resultString = string1.Length.ToString() + ", " + string2.Length.ToString();

Solution 3

there can be null error so please

try the following code

String Result=string1.toString()+string2.toString();
if (string1==null || string2==null) Console.WriteLine("You just got a NullReferenceException (Goe bezig!)");

It will concate your string.
