Based on my understanding, you'd like to set the position of the cursor in
a TextBox to just before the first character of the text.

int position = 0;
public void GotoLine(int LineNum)       // Go to line num...
{
    position = 0;

    for (int i = 1; i <= LineNum; i++)
    FindNext("\n");
}

public void FindNext(string FindValue)      // Find word...
{
    int start = this.TextBox1.Text.IndexOf(FindValue, position);
    int length = FindValue.Length;

    this.TextBox1.Select(start, length);

    position = start + length;
}
