一直覺得repeater不靈活，但是其實如果用后臺拼接html內(nèi)容的話，結合object類型，其實可以變化出多變的內(nèi)容。這里有個需求需要根據(jù)不同的基金經(jīng)理來綁定變動后的基金經(jīng)理內(nèi)容，每個基金經(jīng)理還有特定的ID用來拼接處html超鏈接來跳轉，困難來了，如果知道不同的內(nèi)容的基金經(jīng)理，是一個，二個或者多個呢，多個自然可以用逗號分隔，但是保存出來如何讓repeater綁定呢?。窟@里我采用了eval來實現(xiàn)。具體來看代碼：
首先要在實體類中定義一個標記字段和兩個用來存放基金經(jīng)理名的string數(shù)組或者僅僅是一個基金經(jīng)理，那用object對象最好不過，對于前段和中間都隱藏其具體含義，最后強綁定轉換就行，當然是根據(jù)標記字段來綁定。

后臺代碼就實際來拼接html內(nèi)容：
- public string IsFundMangerNumber(string FundMangerNumber, object JJJLIDArray, object JJJLArray)
- {
- string Show="";
- if (FundMangerNumber == "1")
- {
