复制代码 代码如下:

public class JsonUtil
{
public string ToJson(DataSet dataSet)
{
string jsonString = \"{\";
foreach (DataTable table in dataSet.Tables)
{
jsonString += \"\"\"\" + table.TableName + \"\"\":\" + ToJson(table) + \",\";
}
jsonString = jsonString.TrimEnd(\',\');
return jsonString + \"}\";
}
public string ToJson(DataTable dt)
{
StringBuilder jsonString = new StringBuilder();
jsonString.Append(\"[\");
DataRowCollection drc = dt.Rows;
for (int i = 0; i < drc.Count; i++)
{
jsonString.Append(\"{\");
for (int j = 0; j < dt.Columns.Count; j++)
{
string strKey = dt.Columns[j].ColumnName;
string strValue = drc[i][j].ToString();

Type type = dt.Columns[j].DataType;
jsonString.Append(\"\"\"\" + strKey + \"\"\":\");
strValue = String.Format(strValue, type);

jsonString.Append(\"\"\"\" + strValue + \"\"\",\");

}
jsonString.Append(\"},\");
}
jsonString.Remove(jsonString.Length - 1, 1);
jsonString.Append(\"]\");
return jsonString.ToString();
}
}
