我就废话不多说了，大家还是直接看代码吧~

/// <summary>
    /// 计算字符串在指定text控件中的长度
    /// </summary>
    /// <param name="message"></param>
    /// <returns></returns>
    int CalculateLengthOfText(string message,Text tex)
    {
        int totalLength = 0;
        Font myFont = tex.font;  //chatText is my Text component
        myFont.RequestCharactersInTexture(message, tex.fontSize, tex.fontStyle);
        CharacterInfo characterInfo = new CharacterInfo(); 
        char[] arr = message.ToCharArray(); 
        foreach (char c in arr)
	{
            myFont.GetCharacterInfo(c, out characterInfo, tex.fontSize); 
            totalLength += characterInfo.advance;
        } 
        return totalLength;
    }

补充：用Unity的TextAsset读取TXT文档内容，将物品信息存入字典中

Text Asset 文本资源

Text Assets are a format for imported text files. When you drop a text file into your Project Folder, it will be converted to a Text Asset. The supported text formats are:

文本资源是导入的文本文件的一个格式。当你拖入一个文本文件到你的项目时，他会被转换为文本资源。支持的文本格式有：

.txt .html .htm .xml .bytes

Properties 属性

Text

The full text of the asset as a single string.

物品属性分析

之后需要新建一个文本txt来存放物品的属性，这里以药品为例

TXT文档内容

每一行文本对应一种物品，用逗号分隔，每个值对应属性表里的每一列属性。

之后新建c#脚本解析文本内容

private TextAsset objectsInfoListText; // 新建TextAsset变量
private Dictionary<int, ObjectInfo> objectInfoDict = new Dictionary<int,ObjectInfo>();
void Awake()
{
    objectsInfoListText = Resources.Load("ObjectsInfoList") as TextAsset; // 从Resouces的path中读取到文件
    ReadInfo();
}
void ReadInfo()
{
     string text = objectsInfoListText.text;  // 将文本内容作为字符串读取
     string[] objInfoArray = text.Split('\n'); // 以\n为分割符将文本分割为一个数组
     foreach (string str in objInfoArray)  // 遍历每一行并将每一个药品的值放入类对象中，并存入字典
     {
         ObjectInfo info = new ObjectInfo();
         string[] propertyArray = str.Split(',');
         int id = int.Parse(propertyArray[0]);
         string name = propertyArray[1];
         string icon_name = propertyArray[2];
         string str_type = propertyArray[3];
         ObjectType type = ObjectType.Drug;
         switch (str_type)
         {  
             case "Equip":
                 type = ObjectType.Equip;
                 break;
         【本文由：http://www.1234xp.com/ip.html 提供,感谢支持】    case "Mat":
                 type = ObjectType.Mat;
                 break;
             case "Drug":
                 type = ObjectType.Drug;
                 break;
         }
         info.id = id; info.name = name; 
         info.icon_name = icon_name; info.type = type;
         if (type == ObjectType.Drug)
         {
             int hp = int.Parse(propertyArray[4]);
             int mp = int.Parse(propertyArray[5]);
             int price_sell = int.Parse(propertyArray[6]);
             int price_buy = int.Parse(propertyArray[7]);
             info.hp = hp; info.mp = mp; info.price_sell = price_sell; info.price_buy = price_buy;
         }
         // 将物品信息存储到字典中
         objectInfoDict.Add(id, info);
     }
}
public enum ObjectType
{
    Drug,
    Equip,
    Mat,
};
public class ObjectInfo 
{
    public int id;
    public string name;
    public string icon_name;
    public ObjectType type;
    public int hp;
    public int mp;
    public int price_sell;
    public int price_buy;
}
