You need to use
StringBuilder to solve the efficiency problem of strings.
The String object is immutable. Every time you use one of the methods in the System.String class, you create a new string object in memory, which requires a new allocation of space for that new object. In situations where you need to perform repeated modifications to a string, the overhead associated with creating a new String object can be costly. The System.Text.StringBuilder class can be used when you want to modify a string without creating a new object. For example, using the StringBuilder class can boost performance when concatenating many strings together in a loop.
For your issue, you could use a
StringBuilder object to append your string.
StringBuilder stringBuilder = new StringBuilder(); stringBuilder.Append(test_label.Text); var s2 = "test"; stringBuilder.Append(s2); test_label.Text = stringBuilder.ToString();
This is because when a string is too long, it causes significant memory and computational overhead.
The best solution to this problem is to segment or paginate the content after it exceeds a certain range or load its fragments as you scroll.
