jquery datagrid 后台获取datatable处理成正确的json字符串

1.处理点所有的换行

/// <summary>

/// 去掉换行符

/// </summary>

/// <param name="str"></param>

/// <returns></returns>

public string GetDeleteBR(string strinput){
string p = "\\n|\r\n"; //数据库的的换行是\n

string returnstr = System.Text.RegularExpressions.Regex.Replace(strinput, p, " ");

return returnstr;

}

2.转换成对应的json数据格式的字符串

/// <summary>

/// datatable to json

/// </summary>

/// <param name="count"></param>

/// <param name="page"></param>

/// <param name="dt"></param>

/// <returns></returns>

public string DataTableToJson(int count, int page, DataTable dt){

StringBuilder Json = new StringBuilder();

Json.Append("{");

Json.Append("\"total\":" + count + ",");

Json.Append("\"rows\":[");

if (dt != null){

if (dt.Rows.Count > 0) {

for (int i = 0; i < dt.Rows.Count; i++)

{

Json.Append("{");

for (int j = 0; j < dt.Columns.Count; j++)

{

Json.Append("\"" + dt.Columns[j].ColumnName.ToString() +

"\":\"" + GetDeleteBR (dt.Rows[i][j].ToString())+ "\"");

if (j < dt.Columns.Count - 1)

{

Json.Append(",");

Json.Append("\r\n");

}

}

Json.Append("}");

if (i < dt.Rows.Count - 1)

{

Json.Append(",");

}

}

}

}

Json.Append("],");

Json.Append("\"index\":" + page);

Json.Append("}");

return Json.ToString();

}

return Json.ToString();
