怎么样转换生成的文本文件的编码格式

[flyindirty2008]

请问大家怎么才能使创建的文本文件的编码格式变为ANSI，在C#下面默认的是UTF-8格式的
FileInfo Fi = new FileInfo(“d://ss”);
StreamWriter Sw = Fi.CreateText();

[ericzhangbo1982111]

FileInfo Fi = new FileInfo(“d://ss”);
StreamWriter Sw = Fi.CreateText();
Sw.Encoding=Encoding.ANSII；

不行啊，提示如下错误
Property or indexer 'System.IO.TextWriter.Encoding' cannot be assigned to -- it is read only

[ericzhangbo1982111]

FileInfo Fi = new FileInfo(“d://ss”);

StreamWriter Sw = new StreamWriter("d://ss",Encoding.ANSII);

构造StreamWriter的时候指定编码

[kzxuexi]

private void WriteFile(string path, string strSQL)
{
string strContent;

using (StreamWriter sr = new StreamWriter(path, true,System.Text.Encoding.Default))
{
sr.WriteLine(System.DateTime.Now.ToString()); //记录写入的系统时间
sr.WriteLine();
DataTable table = myDataBase.GetTable(strSQL);
foreach (DataRow row in table.Rows) //把所有数据项写入文件
{
strContent = string.Empty;
foreach (DataColumn column in table.Columns)
{
strContent = strContent + row[column].ToString() + " ";

}
sr.WriteLine(strContent);
}
sr.WriteLine();
sr.WriteLine();
}
} //写入文件
