asp.net如何将DataSet转换成josn并输出

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();

}

}

复制代码使用JsonUtil ju = new JsonUtil();

Response.Write(ju.ToJson(ds));

复制代码如果解析有问题可以把代码中的""""用"\""替换
