替換文字

private void GenerateEntity()
{
    try
    {
        string result = ChangeWords("specific content...");
        txtContent.Text = result;
        ChangeColor();
    }
    catch (Exception ex)
    {
        MessageBox.Show("類生成失敗！錯誤資訊：" + ex.Message);
    }
}
private string ChangeWords(string
 
 content)
{
    //先替換"nvarchar"、"varchar"、"nchar"，再替換"char"
    //不然"nvarchar"、"varchar"、"nchar"就會被替換為
    //nvarstring"、"varstring"、"nstring"不能進行原有規則替換
    string result = Regex.Replace(content, "nvarchar", "string");
    //進行下一步替換的時一定要以上一步替換的返回結果為資料來源而不是content
    //因為content值沒有改變
    result = Regex.Replace(result, "varchar"
 
, "string");
    result = Regex.Replace(result, "nchar", "string");
    result = Regex.Replace(result, "char", "string");
    result = Regex.Replace(result, "tinyint", "int");
    result = Regex.Replace(result, "smallint", "int");
    result = Regex.Replace(result, "bigint", "int");
    result = Regex.Replace(result, "datetime"
 
, "DateTime");
    return result;
}

改變字型顏色

要改變字型顏色一定要使用RichTextBox，普通的文字框不能實現為某些特殊文字新增顏色的功能。

private void ChangeColor()
{
    txtContent.SelectionStart = 0;
    txtContent.SelectionLength = txtContent.Text.Length;
    txtContent.SelectionColor = Color.Black;
    //列註釋不為空時，改變列註釋顏色
    if (listDescription.Count > 0)
    { 
        ChangeKeyColor(listDescription, Color.Green);  
    }
    ChangeKeyColor("namespace", Color.Blue);
    ChangeKeyColor("public", Color.Blue);
    ChangeKeyColor("class", Color.Blue);
    ChangeKeyColor("/// <summary>",Color.Gray);
    ChangeKeyColor("///", Color.Gray);
    ChangeKeyColor("/// </summary>", Color.Gray);
    ChangeKeyColor("int", Color.Blue);
    ChangeKeyColor("double", Color.Blue);
    ChangeKeyColor("float", Color.Blue);
    ChangeKeyColor("char", Color.Blue);
    ChangeKeyColor("string", Color.Blue);
    ChangeKeyColor("bool", Color.Blue);
    ChangeKeyColor("decimal", Color.Blue);
    ChangeKeyColor("enum", Color.Blue);
    ChangeKeyColor("const", Color.Blue);
    ChangeKeyColor("struct", Color.Blue);
    ChangeKeyColor("DateTime", Color.CadetBlue);
    ChangeKeyColor("get",Color.Blue);
    ChangeKeyColor("set", Color.Blue);
}
public void ChangeKeyColor(string key, Color color)
{
    Regex regex = new Regex(key);
    //找出內容中所有的要替換的關鍵字
    MatchCollection collection = regex.Matches(txtContent.Text);
    //對所有的要替換顏色的關鍵字逐個替換顏色    
    foreach (Match match in collection)
    {        
        //開始位置、長度、顏色缺一不可
        txtContent.SelectionStart = match.Index;
        txtContent.SelectionLength = key.Length;
        txtContent.SelectionColor = color;
    }
}

public void ChangeKeyColor(List<string> list, Color color)
{
    foreach (string str in list)
    {
        ChangeKeyColor(str, color);
    }
}
