贴出代码：
var caml = new CamlQuery();
caml.ViewXml =
@"<View>
<Query>
<Where>
<And>
<Eq>
<FieldRef Name='DeleteFlag'/>
<Value Type='Text'>False</Value>
</Eq>
<Neq>
<FieldRef Name='_ModerationStatus'/>
<Value Type='Text'>0</Value>
</Neq>
</And>
</Where>
<OrderBy>
<FieldRef Name='Order0'/>
</OrderBy>
</Query>
</View>";
[解决办法]
感觉你的ModerationStatus应该是int型，Flag应该是Bool型，具体的列表设置你再看看，是不是你设置的Text类型，这个对应SharePoint的“单行文本”。
