[C#, Unity] Unity Text text super box with ‘...’ ellipsis at the end

public void SetTextWithEllipsis(Text textComponent, string value)
        {
            var generator = new TextGenerator();
            var rectTransform = textComponent.GetComponent<RectTransform>();
            var settings = textComponent.GetGenerationSettings(rectTransform.rect.size);
            generator.Populate(value, settings);
            var characterCountVisible = generator.characterCountVisible;
            var updatedText = value;
            if (value.Length > characterCountVisible)
            {
                updatedText = value.Substring(0, characterCountVisible - 3);
                updatedText += "…";
            }
            textComponent.text = updatedText;
        }


Example:

Transform tt = gameObject.transform.Find("Text");
SetTextWithEllipsis(tt.gameObject.GetComponent<Text>(), "fffffffffffffffffffffffff");

[C#, unity] Fixed: The name instantiate' does not exist in the current context

                        Transform cloneTransform = m_fields.GetChild(nColumn).GetChild(nIndex);
                        Transform tempTransform = Instantiate(cloneTransform).transform;
                        tempTransform.SetParent(m_fields.GetChild(nColumn));
                        tempTransform.localPosition = Vector3.zero;
                        tempTransform.localRotation = Quaternion.identity;
                        tempTransform.localScale = Vector3.one;


Answer:

Transform tempTransform = GameObject.Instantiate(cloneTransform).transform;

[C#, Unity] String to Color; Color to String

String to Color
string col = "#FF8400";
this.BackColor = System.Drawing.ColorTranslator.FromHtml(col);


Color to String Color
mycolor = this.BackColor;
string strcol = System.Drawing.ColorTranslator.ToHtml(mycolor);
MessageBox.Show(strcol);

Unity:
public void SetImageColor(string strColor)
{
    Color clr;
    if (ColorUtility.TryParseHtmlString(strColor, out clr))
        this.gameObject.GetComponent<Image>().color = clr;
}
