将包含 xml 代码的字符串转换为 XmlTextWriter 的问题

Question

I have a string variable Writer that recieves xml code from another window . I need to pass this string to textWriter variable but i dont know how to make it readable by textWriter . I tried to convert it to XmlTextWriter but it dont seem to work. How can it be accepted by textWriter ?

textWriter = (XmlTextWriter)XmlTextWriter.Create(new StringBuilder(Writer));

XmlTextWriter textWriter; 

public Question_Redactor(int k, string Writer)
{          
    textWriter =  new XmlTextWriter(Writer);
    InitializeComponent();
}

When the code runs, the following error message is generated:

The system.InvalidCastException: "Unable to cast objects of type" System. Xml. XmlWellFormedWriter "to type" System. Xml. XmlTextWriter"."

Did like jdweng suggested and it worked perfectly

XmlWriter testWriter; 

        public Question_Redactor(int k, string Writer)
        {
            StringBuilder builder = new StringBuilder(Writer);
            XmlWriter writer = XmlWriter.Create(builder);
            testWriter = writer;

            InitializeComponent();

          
        }
