CS1002#

; expected

Resolution#

This error occurs in two situations:

First, check if your statement requires a semicolon.

What statements need semicolons?#

🔴 Don't use a semicolon#

Statements followed by a block are the common place to exclude a semicolon, blocks are often defined by their opening and closing braces, { and }, which can sometimes be omitted in single-line cases.

warning

If you use a semicolon after a block statement it will become an empty statement, and the following block will be disconnected from the preceding statement, causing it to do nothing.

if (example == null); // <- extra semicolon (;)
{
    Debug.Log($"{nameof(example)} is null!"); // This will always print because the previous selection statement has a semicolon!
}

If you are confused, look at example code to see if yours needs a semicolon.

Adding a semicolon#

Add a semicolon ; to the end of your line.
If all errors on that line go away, it's likely the correct solution. Otherwise you may have an incorrectly written statement.

Example#

public void Start()
{
    transform.position = _targetPosition;
    transform.rotation = _targetRotation  // Missing semicolon, add a ; here.
}
information

If your error isn't underlined in red you must configure your IDE.

Fixing an incorrectly written statement#

Statements can be written incorrectly in extremely varied ways. Compare your code structure with a functioning example to see what you're missing.

Whitespace in C##

Whitespace (spaces, tabs, and newlines) is not significant in C#, functionally a piece of code can have all tabs and newlines removed and it will still run1, you can also add extra newlines to make multi-line statements. We instead require a terminator to tell the compiler where a statement begins and ends.

  1. Spaces may be significant when separating keywords and names. Whitespace is significant inside of strings and characters.
