Question

I’m appending string variable text, after appending a line throws System.OutOfMemoryException?
Can any one explain why it is throwing error.

 str+="something  Text"

 str+="something  Text"

and lastly I assign it to a lable text

When I assign the value of str it throws exception…..

Probably you’re trying to concatenate a lot of strings. Each time you change/concat strings a new string will be produced, because string is an immutable type.

Try using StringBuider to get your big-big string 🙂

var builder = new StringBuilder();
builder.Append("something  Text");
builder.Append("something  else");
builder.Append("etc.");
builder.ToString();
